Rome Around Trier: 37 Roman Sites in Four Countries

Trier is usually read as a Roman city. It reads better as a Roman address, the place where an empire kept its office while the work happened somewhere else. The monuments stayed inside the walls. The quarries, presses, estates and roads that built and fed them, and the graves of the people who paid for them, are scattered across four countries, in villages most visitors drive through on the way to somewhere with a museum shop.

This is a reading of that wider territory, chapter by chapter. It starts at the city gate and ends in a small Saarland village above a gladiator floor. Some chapters are major sites. Some are a strip of wall in a forest. They belong together because each one answers a question the city alone cannot: where the stone came from, who paid, what the roads carried, and what people did with Rome once Rome had gone.

Part One. Trier: The Stage

Porta Nigra

The best-preserved Roman gate north of the Alps was never finished. Built around 170 AD, its sandstone blocks still show the rough bosses the masons meant to dress later, and the holes where iron clamps once held the stones together without mortar. Later still is the colour. The black that gave the gate its medieval name is weathering, not design.

It survived because it stopped being a gate. In the eleventh century a hermit named Simeon had himself walled into the east tower, and after his death the archbishop turned the whole structure into a double church. In 1804 Napoleon ordered the church additions removed, and the Prussians finished the job. They chose to keep the Romanesque apse on the east side, and it still clings to the Roman gate, the last visible piece of a church that stood here for eight centuries. What stands today is a restoration of a building that Rome left incomplete and the Middle Ages kept alive by misusing it.

Aula Palatina

Constantine’s throne hall, built around 310, is a single room, 67 metres long including the apse and 33 metres high, without one interior column. It is the largest surviving single-room interior of the Roman world. It was designed to make a visitor walk the full length toward the emperor and arrive feeling small.

The bare red brick that passes today for the Roman look is the one thing the Romans never saw. Outside, the walls were plastered and painted, and fragments of that painting still cling to the window reveals of the north and west walls, a survival without equal north of the Alps. Only those two walls are largely original Roman masonry; the south and east sides date from the nineteenth century and the post-war years. In between, the hall became part of the archbishops’ palace, lost its south and east walls in 1614 to make way for the elector’s palace, was restored by the Prussian king as a Protestant church in 1856, and burned in 1944. The interior you walk into now is the post-war answer to a question nobody in Rome would have asked: what should power look like once the emperor has left?

Imperial Baths (Kaiserthermen)

Begun around 300 as one of the largest bath complexes of the empire, the Kaiserthermen never ran hot water. Work stalled, probably around 316, a pause usually linked to Constantine moving his court away. In the last quarter of the fourth century, under the emperors Gratian and Valentinian II, work resumed with a different plan: the unfinished baths were converted, most likely into barracks, and the hot rooms never got their furnaces.

The best part is underground. A network of service tunnels, built for the workers who carried fuel and ash, runs beneath the ruins and is open to walk. Above ground, the ruins were later built into the medieval city wall, and a city gate even ran through them. A bath that never bathed anyone ended up defending the city.

Barbara Baths (Barbarathermen)

The older imperial baths, built in the second half of the second century, were the ones that actually worked. At the time, only the Baths of Trajan in Rome were larger: the complex covered 172 by 240 metres.

Very little stands, and the Romans are not to blame. From the twelfth century a local family, the von der Brücken, lived in part of the ruins and turned them into their castle, which kept them standing. Then in 1611 the Jesuits began quarrying the walls for their new college, and in 1675 French troops blew up what was left to clear the ground around the city. Today a walkway crosses the foundations and the hypocaust pillars, and the scale has to be read from the floor plan. It is a useful lesson early in the route. The Roman buildings that functioned best are often the ones that left the least behind.

Viehmarkt Baths (Viehmarktthermen)

In 1987, digging for a bank building and an underground car park under the Viehmarkt square, builders struck a large Roman building with the layout of baths. It replaced a block of houses around the middle of the second century; its heating was added later, and archaeologists still debate when it actually served as baths. They dug so fast that part of the evidence was damaged, and the project had to be halted and redesigned to save the ruins. Above them lay the foundations of a seventeenth century Capuchin monastery, and above those the modern square. The find came a year too late: Trier’s Roman monuments had been inscribed on the UNESCO World Heritage List in 1986, and the so-called Viehmarkt baths were not among them.

The architect Oswald Mathias Ungers enclosed the whole find in a glass box in 1998. From inside you see the layers as a single cut through time: Roman masonry at the bottom, monastic cellars above, the street at eye level through the glass. It is the clearest demonstration of Layering in the city, and the only Roman site in Trier where the present is built into the display rather than kept politely outside.

Amphitheatre

Built in the second century into the slope of the Petrisberg, the arena held around 18,000 spectators. The Romans dug half of it out of the hill and piled the spoil into the other half, so the structure is as much earthwork as architecture.

Go down the stairs in the centre of the arena floor. Beneath it is a cellar where the machinery once sat: lifts, ramps, cages, the backstage of the games. Later the amphitheatre was folded into the city wall and served as Trier’s eastern gate. In the Middle Ages it became a quarry like everything else. The vineyard above it now is not decoration. It is the hill taking the site back.

Roman Bridge (Römerbrücke)

The stone piers of the bridge were set between 144 and 152 AD, dated precisely by the timber beneath them, and they still carry cars and buses. The Romans laid a timber deck across them. Stone arches came only in 1343, under Archbishop Balduin, and the ones you see today were rebuilt in 1716 to 1718 after French troops blew the bridge in 1689.

The bridge also dates the city. Wooden piles from the first crossing at this spot have been dated to 18 and 17 BC, which is the closest thing Trier has to a birth certificate. Before there was a forum or a gate, there was a way across the river. The city grew outward from a piece of infrastructure, and the infrastructure is still in use.

Trier Cathedral

The oldest cathedral in Germany stands on the site of a fourth century Christian complex, built over part of an imperial residence. Legend says Helena, Constantine’s mother, gave her house to the church. Archaeology has found painted ceilings from the palace below the floor.

Outside the entrance lies a broken granite column, the Domstein. It once stood inside the first, Constantinian cathedral. Local legend says the devil threw it there. The truth is more prosaic and more interesting: the column came from a quarry in the Odenwald, roughly two hundred kilometres away, and in 1614 its pieces turned up under the cathedral floor while foundations were being laid for a new altar. They were dug out, but nobody knew what to do with some sixty-five tonnes of stone, so they were simply laid by the door.

The museum is where the countryside comes to town. The tomb reliefs from Neumagen are here, including the wine ship. So is the largest preserved hoard of Roman gold coins, some 2,650 aurei, of which 2,518 survive in the museum, buried in a cellar around 196 AD and found in 1993 during construction work, another underground car park in a city that cannot dig without finding Rome.

Visit it before the rest of the route, not after. The reliefs show the people the monuments never mention: people bringing money to a collector’s table, a teacher seated between two pupils, and a third boy arriving with wax tablets. For a long time he was read as a latecomer; the museum now describes him as the younger brother, still learning to write. They are the cast of the chapters that follow.

Part Two. The Moselle: The Economy

Ruwer Aqueduct, Waldrach

A city of baths needs water it cannot find at home. Around the end of the first century, Roman engineers tapped the Ruwer, a small tributary valley northeast of Trier, and built a covered channel to carry its water into the city on a gentle, constant gradient.

At Waldrach, original stretches of the conduit survive, alongside a reconstructed section built from ancient blocks. There is nothing heroic to look at: no arches, only a channel built here of heavy sandstone blocks to hold back the pressure of the slope. The one arched bridge on the line was taken down in the early nineteenth century and reused for a road bridge. That is the point. The arches of an aqueduct are what we photograph, but most of the system ran low and invisible, following the contour of the land. The baths in town were the performance. This was the plumbing.

Imperial Villa of Valentinian I, Konz

Where the Saar meets the Moselle, a few kilometres upriver from Trier, stood a large late Roman residence, usually identified as a country retreat of Emperor Valentinian I. In the summer of 371, several imperial laws were issued from here, dated Contionacum, which historians identify with Konz.

Most of the villa was lost when the new church of St Nicholas was built; beside it stands a fragment of the cold-water basin, about four metres high. It is a modest site with an immodest fact behind it: if the identification is right, for at least one summer the government of the western empire was run from a riverside villa at a confluence most travellers now cross without noticing. Power, in the late empire, moved around. Its furniture stayed behind.

Igel Column (Igeler Säule)

In the village of Igel, beside the main road toward Luxembourg, a sandstone pillar rises twenty-three metres, carved on every face. It was raised in the first half of the third century by the Secundinii, a family of cloth merchants, and the reliefs show their trade with unusual frankness: bales packed, carts on the road, fabric held up for inspection, accounts settled at a table.

Across the region, pagan tombs were broken up for building stone. This one survived because medieval Christians believed one scene showed the wedding of Constantius Chlorus and Helena, the parents of Constantine. A misreading saved the largest Roman pillar tomb north of the Alps still standing where it was built. Nobody corrected the error until it no longer mattered.

Villa Urbana, Longuich

Downriver from Trier, on a terrace above the Moselle at Longuich, archaeologists uncovered a large country villa, and part of its bath wing has been rebuilt to roof height. The site looks out over the river and its vineyard slopes.

The view is the argument. Villas of this kind were built to be seen and to look out: they told a guest that the owner’s wealth lay in the land around them. Standing on the terrace, the relationship is still legible: the house watches, the slope works.

Villa Rustica, Mehring

A few bends further, in the middle of Mehring, the manor house of a Roman estate has been partly rebuilt: a façade with two corner towers and a colonnade between them. The house went up in the second century and grew in the third and fourth to 34 rooms, one of the largest villas in the Trier region.

The most telling find here is a stone, not a wall. The villa’s decoration included green diorite from the imperial quarries of Upper Egypt, the same stone used in the vestibule of Constantine’s throne hall. A landowner on the Moselle was ordering from the same source as the emperor. In the fourth century the river was lined with estates, and Mehring shows how rich they could be.

Neumagen-Dhron: The Wine Ship and the Fort

The poet Ausonius, coming over the Hunsrück from Bingen around 370, reached the Moselle at Noviomagus and called it the famous fort of the divine Constantine. The builders of that fort found much of their stone in the cemetery. Dozens of funerary monuments from the previous two centuries were cut into blocks and stacked into the foundations.

When the foundations were opened in the late nineteenth century, the dead came out preserved precisely because they had been buried a second time, inside the wall. Among them was the wine ship: a stone boat loaded with barrels, oarsmen at the benches. On a second, fragmentary ship from the same finds, the helmsman sits beside a cask and grins. The original is in the Landesmuseum in Trier. A copy stands in the village. The grin is the detail worth the journey. Forts are built in fear. The stones inside this one remember a society that had once been relaxed enough to carve a joke about wine into a grave.

Stella Noviomagi, Neumagen-Dhron

Moored on the riverbank is a full-size reconstruction of a Roman river ship modelled on the stone original, oars and all, which takes passengers out on the Moselle in season. Apprentices of the Trier Chamber of Crafts built it in 2007.

It is easy to dismiss as entertainment, and the ship carries an engine as well as oars. Groups can charter the ship and take the 22 oars themselves, and that is the version worth doing. Row the hull upstream for ten minutes and you understand why the whole wine economy of the valley moved at the pace of the current. The reconstruction cannot give you Rome. It can give you Roman time, which is more than most museums manage.

Roman Wine Press, Piesport

On the western edge of Piesport, roadworks in the vineyards in 1985 uncovered what is considered the largest Roman wine press north of the Alps, a fourth century installation of treading floors, basins and channels. Its seven basins held around 43,500 litres, and the archaeologist Karl-Josef Gilles calculated that it could have served up to fifty hectares of vines.

The upper parts have been reconstructed. What matters is the scale. A press this size means vineyards run as an industry, labour organised around them, and a market large enough to absorb what came down the river. Ausonius described the Moselle slopes planted with vines to the ridge. He was looking at a production landscape and writing it as pastoral.

Roman Wine Press, Brauneberg

Opposite Brauneberg, at the foot of the Juffer slope, archaeologists found two Roman presses in 1990, the second only months after the first and right beside it.

On its own it would be a minor stop. Placed in sequence it changes the reading of the valley. Until 1977, archaeology had no direct proof of Roman winemaking on the Moselle at all, only poems and tomb reliefs. Within fifteen years, seven presses had turned up on the middle Moselle. One large press can be an anomaly. Seven describe a system. The Moselle was a Roman wine district with a river running through it.

Roman Wine Press, Erden

The third press sits at Erden, at the foot of one of the steepest vineyard slopes on the river, below the Erdener Treppchen. The press found here in 1992 dates from the mid-third century. In 1998, fifty metres to the east, work on yet another car park uncovered a second one that appears much older, the oldest known on the Moselle; a village association later raised the money to secure it and open it to visitors.

Stand here and look up. The vines still climb the same rock, the terraces still demand the same labour, and the grapes still come down the same gradient to be pressed near the water. The press has stopped. The logic that put it here has not. In most of this route Rome survives as stone. On the middle Moselle it survives as a habit.

Part Three. Eifel and Hunsrück: The Boundaries

Roman Quarry (Pützlöcher), Kordel

In the Kyll valley north of Trier, a footpath leads through the woods to a series of hollows cut into a sandstone cliff. These are the Pützlöcher, a Roman quarry, and the rock faces still carry the marks of the tools that split them.

Before the stonecutters came, Roman miners dug here for copper ore, and their shafts still drop into the rock. Then the cliff became a quarry for the Porta Nigra. A name, MARCI, recorded here also appears on blocks of the gate in Trier, perhaps the mark of a stonecutter, though what exactly the name stood for is uncertain. Stand in the cut and the city reverses itself: the gate, the walls, the baths are no longer objects but absences, shapes taken out of a hillside and carried downriver. Every monument in town has a negative somewhere in the forest. This is one of them.

Langmauer, Herforst

In the fourth century, someone ordered a wall about seventy-two kilometres long to be built through the Eifel north of Trier, enclosing roughly 220 square kilometres of forest, field and farmland. It was never a defensive work and could not have stopped an army. Two building inscriptions found near Herforst show that military units did the work.

Most historians read it as the boundary of an imperial domain: a political line drawn across the countryside, deciding whose land lay inside it. In the forest near Herforst, stretches about a metre high survive on their original foundations, easy to walk past. Near the village, a twenty-metre section has been rebuilt. The order it imposed has vanished entirely. The line is still there.

Villa Otrang, Fließem

In a quiet valley near Bitburg, Villa Otrang preserves the mosaic floors of a large country estate, with a temple precinct nearby. The remains were struck during fieldwork in 1825. The Trier Society for Useful Research bought the site, and after the Prussian crown prince visited the excavations in 1838, protective halls went up over the mosaics and the state took over their care, making Otrang an early model of conservation in Germany. The halls are now listed monuments themselves.

That is the double reading here. The floors tell you how a Roman landowner wanted to live. The sheds over them tell you how nineteenth century Prussia wanted to be seen, as the responsible heir of antiquity in a province it had only recently acquired. The villa is Roman. The way you are looking at it is Prussian.

Late Roman Fort Walls, Bitburg

Bitburg began as Beda, a roadside settlement on the route from Trier to Cologne that stretched almost a kilometre along the road. In the fourth century a fort went up on less than two hectares: walls 3.8 metres thick, thirteen round towers, two gates. Stretches of those walls still stand in the town centre.

Around 1340 the Roman ring was built into the medieval town wall and stayed in use into modern times. That is why Bitburg counts among the best-preserved late Roman fortifications north of the Alps, and why the old town is still drawn by its outline. A town can lose almost every Roman stone and keep the Roman shape. Bitburg is a fort you walk through without being told.

Archaeological Park Belginum, Morbach-Wederath

On the Hunsrück ridge east of the Moselle, along the Roman road from Trier to Mainz, lay Belginum, a Roman roadside town beside a burial ground already in use since the Celtic Iron Age. People were buried here for some eight centuries, and archaeologists have found about 2,500 graves.

That continuity is the reason to come. At Belginum you can follow people who were Treveri before they were Romans, and who went on burying their dead in the same ground as the language, the coins and the gods changed around them. Romanisation, in most books, is an event. In this cemetery it is a slow change of habits, one generation at a time.

Gallo-Roman Temple District, Tawern

On the Metzenberg above the village of Tawern, beside the Roman road from Metz to Trier, stood a precinct of temples, one of them dedicated to Mercury. It has been partly reconstructed on its original foundations, and a steep walk through the woods leads up to it.

The location explains the cult. Travellers coming north from Metz reached this hill and saw Augusta Treverorum for the first time, fifteen kilometres away in the valley. It is easy to imagine them leaving an offering for a safe arrival before they had even arrived. Mercury was the god of roads and trade. Here he also guarded the view.

Part Four. Saarland: Reconstruction and Original

Roman Villa Borg, Perl-Borg

Since 1994, an entire villa has been rebuilt on its excavated Roman foundations near Perl: the manor house, baths, gardens and a tavern that serves dishes from Roman recipes. The walls stand, the roof tiles are red, the rooms are furnished.

Only the foundations are original. That is the reason to come, and to come first. Borg answers the question every ruin leaves open, what did this look like, with total confidence. Walk through it carefully and notice how much of that confidence is educated guesswork: the colours, the furniture, the height of a roof nobody has ever seen. Much of it was modelled on other villas in the region, Echternach among them, and the tavern stands in a wing the original never had. Then drive down the hill.

Roman Villa Nennig, Perl-Nennig

In 1852, a farmer digging in his field at Nennig struck the edge of a mosaic floor. The floor, laid in the third century in the reception hall of a vast villa with a 140-metre façade, covers some 160 square metres and shows gladiators, wild animals and musicians at the games, including a rare depiction of a water organ, in colours that have barely faded. It is among the finest Roman mosaics north of the Alps.

The house above it is gone; only its foundations survive, and the floor lies under a hall raised to protect it. Borg has a house and almost nothing original. Nennig has an original and no house. Standing between the two, a few kilometres apart, you are forced into the question reconstruction prefers to avoid: which of them is closer to Rome?

Part Five. Luxembourg: The Other Bank

Roman Villa, Echternach

In 1975, during work on a recreational lake just outside Echternach, builders exposed the foundations of a Roman villa so large it is better described as a palace. It measured 118 by 62 metres, with a porticoed courtyard and pool, its own baths, marble-clad walls and mosaic floors, and its plan is now laid out beside the water with a small museum pavilion.

Building began around AD 70, and researchers think the estate most likely bred horses for sale to the Roman army. Echternach is famous for its medieval abbey. Centuries before the monks arrived, a short walk away, someone had already built a monument to the idea that this valley was worth ruling. The town’s name is thought to come from the estate’s own, Epternacum, and the monks of Willibrord may have used its ruins as a quarry.

Ricciacum and the Gallo-Roman Theatre, Dalheim

On the plateau above Dalheim, on the road from Metz to Trier, lay Ricciacum, a roadside town with houses, baths, temples and a theatre for a few thousand spectators. An excavated residential quarter and the theatre are open to visitors. The town was founded around 18 BC as a station on Agrippa’s road, in almost the same years the first bridge piles went into the Moselle at Trier.

Dalheim is the same road as Tawern, seen from further south. A traveller would have stopped here, washed, eaten, perhaps watched a performance, and moved on the next morning toward the capital. Empires are usually told through their cities. They were held together by places like this, a day’s journey apart, where nothing remarkable happened every day.

National Museum of Archaeology, History and Art (MNAHA), Luxembourg City

The national museum, on the Fish Market in the oldest part of Luxembourg City, holds the archaeology of the whole country. Its centrepiece for this route is the mosaic from Vichten, uncovered by archaeologists in 1995, a year after a farmer struck the villa during earthworks and said nothing until an anonymous tip reached the authorities: a Roman floor depicting the nine Muses with Homer at its centre.

Place it next to Nennig in your memory. Both surfaced on farmland. Both are floors whose houses have disappeared. Nennig stayed where it was found and was given a hall. Vichten, laid by a workshop from Trier around 240, was lifted, moved and placed in a museum in the capital, with a copy left in the village. Two answers to the same question, and each one changes what the floor means. In situ it is a room. In a museum it is a national treasure.

Titelberg

On a plateau in the southwest of Luxembourg, near the French and Belgian borders, lay one of the principal oppida of the Treveri, a fortified Celtic town that minted its own coins in the first century BC. When Rome arrived, the plateau was not destroyed. It was gradually absorbed, its public sanctuary rebuilt in Roman form, while political weight drifted toward the new roads and the new capital on the Moselle.

Titelberg is where this story starts, before Trier existed. It is mostly fields now, with excavation areas and a few marked paths. That emptiness is its lesson. Rome did not have to burn the Treveran capital. It lived on as a small Roman town into the fifth century. It simply stopped mattering once a better address stood on the Moselle.

Roman Vicus and Baths, Mamer

On the road from Reims to Trier, west of present-day Luxembourg City, the Roman settlement at Mamer grew up as a stopping place, with a public bath. It was found in 1972, and its walls have been rebuilt to half a metre so the plan can be read.

Mamer belongs with Dalheim and Tawern as part of the same infrastructure, approached from another direction. Roman Trier was reachable from Gaul by more than one road, and each road had its own string of baths, inns and shrines. The capital was the knot. These towns were the thread.

Villa “Miecher”, Goeblange-Nospelt

In the woods near Goeblange lie the remains of a large Gallo-Roman estate: at least seven stone buildings on five hectares inside an earth bank, including a luxurious manor house, an older one, a small temple and outbuildings. Building began in the early first century, and the site was rediscovered in 1964.

The interesting thing here is the date, not the size. Around AD 30, shortly after a Treveran revolt was crushed, the owner broke with Celtic tradition and built himself a mausoleum on the Roman model. Romanisation here looks less like a decree than a personal decision by one landowner, taken at a well-chosen moment. In the late third century, during Germanic raids, the estate was turned into a fortified burgus; under Constantine the defences came down and the villa had one more short flowering.

Musée d’Histoire(s), Diekirch

In the north of Luxembourg, the town museum of Diekirch displays a Roman mosaic in its basement, from the large villa that once stood where the town is now. The church of Saint-Laurent next door was built over the remains of a large Roman hall belonging to the villa.

Diekirch is a reminder that the Roman countryside did not stop at the vineyards. The estates reached into the hills of the Ardennes edge as well, wherever there was land to farm and a road to market. It is also a small, local museum, and that matters. Not every Roman floor ended up in a capital. Some stayed with the town that found them.

Part Six. Belgium and France: Where the Roads Came From

Orolaunum, Arlon

Arlon sat on the road from Reims to Trier, and in the late third and fourth centuries, like Neumagen, it closed itself behind a wall. Like Neumagen, it built that wall partly from its own graves. Sculpted funerary monuments, cut into building blocks, went into the foundations, and when the defences were later taken apart, the dead came back out.

The archaeological museum in Arlon holds one of the richest collections of Roman funerary sculpture in the region: merchants, families, carts, scenes of daily work. The Roman Tower and surviving stretches of wall stand nearby. Arlon matters because it makes Neumagen a pattern rather than an accident. Across the province, in the same anxious decades, towns did the same thing for the same reason, and the reason is written in the order of the stones.

Gorze Aqueduct, Jouy-aux-Arches

South of Metz, more than fifteen tall stone arches stand in the middle of the village of Jouy-aux-Arches. They are what remains of the aqueduct that carried water from the springs of Gorze to Roman Metz, crossing the Moselle on a bridge of arches more than a kilometre long. It was built in the early second century and stood on more than a hundred piers.

The channel at Waldrach keeps low to the ground. These cannot be missed. Together they describe the full vocabulary of Roman water engineering, the hidden channel and the monumental crossing, built by the same civilisation for the same purpose. The village has grown around the arches and even carries them in its name. To Jouy, they are simply the oldest building in the neighbourhood.

Musée de la Cour d’Or, Metz

Metz was Divodurum, the city at the southern end of the road that runs through Dalheim and Tawern to Trier. When its main museum was being enlarged in 1932, workers found Roman baths underneath, and visitors now walk among the excavated walls inside the building.

Ending the route abroad here is deliberate. For a traveller in the fourth century, Metz was where the journey to Trier began. Read in that direction, every site on the road north becomes a station of arrival: the baths at Dalheim, the temple at Tawern with its first view of the capital, the bridge at the end of the road. The capital was built to be reached from here.

Epilogue. Schloss Berg, Nennig

(Anzeige / Ad)

Every route through Roman country eventually arrives at a simple question: where do you stay? The Romans answered it with a villa. In Nennig, a few minutes’ walk from the gladiator floor, the answer has not changed.

Victor’s Residenz-Hotel Schloss Berg sits among the vineyards where Germany, Luxembourg and France meet, in two buildings: a Renaissance castle and a Roman villa. Rome here goes deeper than the façade. The villa’s rooms come with heavy drapes, gilded headboards and art after antique models, the spa is modelled on Roman baths, and the wine bar bears the name of Julius Caesar. The castle holds one of the great kitchens of Europe. Christian Bau brings France and Japan together so convincingly that his restaurant has held three Michelin stars without a break since November 2005. No chef in Germany today has kept the highest rating longer.

Part Four left a question open: which is closer to Rome, the rebuilt villa at Borg or the original floor at Nennig? Schloss Berg offers a third answer, and perhaps the most Roman of the three. A villa on the Moselle was never a museum. Guests arrived after a long road; the owner met them, sent them to the baths, poured wine from his own slopes and led them out to a terrace where the vines ran to the horizon. Borg restores Roman walls. Schloss Berg carries on Roman hospitality, on the same river, among the same vineyards.

Even the mix under one roof, Italian cooking, a German beer garden and French-Japanese cuisine of the highest order, is deeply Roman. The province always lived at a crossroads: Celtic gods took Latin names, Moselle wine went downriver to Trier, and a Treveran landowner walked across Greek Muses on his own floor. The Moselle has been mixing worlds for two thousand years, and here it does so in style.

Two kilometres away, the Moselle runs past three countries at once: Germany on this bank, Luxembourg on the other, France a little way upstream. Close by stands the Mahlknopf, a Roman burial mound, a reminder of the ground the hotel is built on.

The Romans would have recognised the geography if not the borders. This was one province, one road network, one wine trade, one set of gods with local names. The lines that now separate it are younger than the mosaic by more than fifteen centuries, and they cut straight through the territory this guide has been reading as a whole.

After thirty-seven chapters, the pattern is hard to miss. In the city, Rome survived by being turned into something else: a church, a palace, a wall, a glass box on a market square. In the countryside, it survived by being ignored, buried in a fort, left in a field, forgotten under a vineyard until a farmer’s spade found it.

Trier kept the monuments. The land kept the evidence.

Less than a kilometre down the road, the floor at Nennig has been waiting since the third century for guests in a house that is no longer there. The house is gone. The guests, it turns out, never stopped coming. They simply stay a little further down the road, in a villa where the table has been laid for them again.
