Trier
Roman monuments, imperial history and the vineyards of the Moselle Valley
Discover Trier, one of Germany’s oldest cities, where Roman gates, imperial baths and ancient basilicas stand alongside medieval churches and Moselle vineyards. Follow the story of Augusta Treverorum from the Roman Empire to today’s Rhineland-Palatinate.
INTRODUCTION
Welcome to Trier
Trier sits on the Moselle River close to Luxembourg and preserves an extraordinary concentration of Roman monuments. Founded as Augusta Treverorum under Augustus, it grew into a major imperial city whose surviving architecture still shapes the old town.
Spend time at the Porta Nigra, the Aula Palatina and the imperial bath complexes, then explore the cathedral, medieval market square and archaeological collections. Trier also makes a rewarding base for Moselle walks, vineyard villages and visits to nearby Luxembourg.

WHY VISIT
Why Visit Trier?
Trier brings the Roman world unusually close: monumental city gates, late-antique imperial buildings and archaeological sites stand within walking distance of medieval streets, churches and the Moselle waterfront.
01
Porta Nigra & Roman City Gates
The immense dark-stone Porta Nigra is Trier’s best-known Roman landmark. Built around the late second century, it survives as a remarkable reminder of the fortified city of Augusta Treverorum.
02
Roman Imperial Capital
During the third and fourth centuries Trier became a leading imperial residence. Constantine and other emperors left ambitious public buildings, grand baths and a monumental audience hall.
03
Cathedral & Medieval Heritage
Trier Cathedral and the adjacent Church of Our Lady link late-antique Christian origins to centuries of medieval architecture, religious power and pilgrimage.
04
Moselle Valley & Wine Landscapes
Beyond the historic centre, the Moselle bends between vineyards and wooded hills. Scenic paths and wine villages add a relaxed landscape dimension to a history-focused city trip.
HISTORY
A Short History of Trier
Trier was established as Augusta Treverorum in the Roman era, traditionally dated to around 16 BC. Its location on the Moselle helped it develop into a prosperous administrative and commercial centre in the province of Gallia Belgica.
In late antiquity Trier became a residence of Roman emperors, especially under Constantine in the early fourth century. The Porta Nigra, Aula Palatina, amphitheatre and bath complexes testify to the city’s imperial importance. Early Christianity also helped establish Trier as a major ecclesiastical centre.
In the Middle Ages the archbishops of Trier became influential prince-electors, while merchants traded along the Moselle. The city later passed through French and Prussian rule, suffered wartime damage and preserved or restored much of its heritage. Trier’s Roman monuments, Cathedral and Church of Our Lady were inscribed on the UNESCO World Heritage List in 1986.

TOP SIGHTS
Top Sights in Trier
These eight sights trace Trier’s evolution from a Roman provincial capital to an influential medieval religious centre. Most are walkable from the historic centre, although the amphitheatre and bath sites deserve extra time.
1
Porta Nigra
Trier’s striking Roman gate was constructed around AD 170 and later served as a church. Walk around its massive sandstone towers and, where access permits, explore the upper levels.
2
Trier Cathedral (Dom)
Germany’s oldest episcopal church complex incorporates ancient foundations and later Romanesque, Gothic and Baroque elements. The cathedral and its treasury offer a window into nearly 1,700 years of Christian history.
3
Aula Palatina (Basilica of Constantine)
This immense brick audience hall belonged to the imperial palace complex of Constantine’s era. Now used as a Protestant church, it preserves the scale and ambition of late-Roman Trier.
4
Imperial Baths (Kaiserthermen)
The surviving walls and underground service corridors reveal the engineering behind one of the Roman Empire’s largest bath projects, which was altered before completion.
5
Roman Amphitheatre
Built into a hillside outside the old Roman walls, this arena once hosted public spectacles. Explore its seating area and surviving underground spaces for a vivid sense of ancient city life.
6
Hauptmarkt & Medieval Old Town
The historic main market is framed by colourful townhouses, the market cross and St. Gangolf’s Church. It is an excellent starting point for a walk through medieval Trier.
7
Church of Our Lady (Liebfrauenkirche)
Beside the cathedral, this elegant 13th-century Gothic church is celebrated for its centralised plan and sculptural details. It forms part of Trier’s UNESCO-listed heritage.
8
Rheinisches Landesmuseum Trier
One of Germany’s most important archaeological museums displays Roman mosaics, sculptures, tomb monuments and objects that illuminate daily life in Augusta Treverorum.
