A Brief History Of Trier
Trier, Germany’s oldest city, boasts a rich and complex history. Its roots extend back to the early Neolithic period, with evidence of settlements dating back to 5500-4500 BC. The city’s true birth, however, came in 16 BC when Emperor Augustus founded Augusta Treverorum, a strategically positioned settlement that rapidly developed into an administrative and commercial center.
Trier became the capital of the Roman province, Gallia Belgica, and its significance grew further as it joined the breakaway Gallic Roman Empire before returning to the Roman Empire. By the third century, Trier had become an imperial seat and, from 293 to 395, served as one of the residences of the Western Roman Emperor.
Constantine the Great, who reigned from 306 to 337, expanded and fortified Trier, adding a stadium to the amphitheater and constructing the Imperial Baths and his throne room/audience hall, which is now known as Konstantin-Basilika.
These constructions, alongside contributions to what would become Trier Cathedral and Liebfrauenbasilika, illustrate Constantine’s impact on the city’s development.
While Germanic tribes began attacking Trier around 350 AD, these assaults were largely repelled. However, the fifth century saw Trier suffer from four sacks by the Franks and one by the Huns, leading to a significant decline in its population.
Trier became part of the Kingdom of Lorraine in 843, only to join the East Frankish Empire in 870, eventually becoming part of Germany. The city became an archbishopric in 815, with its archbishops holding sway over a vast territory.
They later became one of the seven Electors of the Holy Roman Empire in the late 12th century. Trier’s fortunes fluctuated throughout the Middle Ages, marked by periods of prosperity and decline. This era saw the city endure various wars, including the Thirty Years’ War, the Franco-Spanish War, and the Nine Years’ War.
The French Revolution brought an end to the Electorate of Trier in 1794, with the city becoming part of France. In 1814, Prussia captured Trier, and it became part of the Kingdom of Prussia in 1815. Despite facing economic setbacks, Trier witnessed growth from 1842 with the inclusion of Luxembourg in the German Customs Union.
Trier suffered extensive damage during World War II, but it was rebuilt after the war as a cultural and commercial hub. Today, Trier stands as a testament to its rich history, attracting tourists from around the world to explore its Roman ruins, medieval architecture, and cultural heritage.
Exactly How To Spend One Day In Trier
One day in Trier is not enough to experience everything, but it is enough time to get a nice introduction to the city and to visit most of the amazing range of UNESCO World Heritage sites. Simply follow the below Trier itinerary stop-by-stop for an incredible day.
It’s been designed to be completed by foot. Just one stretch is 20 minutes walk so you may want to bus this if you are getting tired.
Stop 1: Porta Nigra
Perhaps Trier’s most iconic attraction, the UNESCO World Heritage listed Porta Nigra (translating to “Black Gate”) is a monumental testament to Roman engineering. Constructed around 170 A.D., this ancient city gate is known for its colossal size and the darkened color of its sandstone, a result of centuries of weathering.
When visiting, you can marvel at the intricate details of Roman craftsmanship, walk through the same passages ancient Romans once did, and climb to the upper tiers for a captivating view over Trier.
The gate’s historical importance and preservation make it a must-see, providing insight into the Roman era in Germany and offering a tangible connection to the past.
I recommend you start here and enter the city via this gate. There’s no better way to arrive in Trier than the way people have for thousands of years.
Stop 2: Hauptmarkt (Main Market Square)
Next keep walking straight ahead to the heart of Trier in Hauptmarkt.
This lively square is surrounded by beautifully restored medieval buildings, colorful facades, and the iconic St. Gangolf’s Church, offering a vibrant atmosphere for lunch, people-watching, and shopping.
Each corner of the square tells a story, from the market cross that marks its center to the intricate details of the surrounding buildings, including the Steipe and Marktbrunnen (Market Fountain) from 1595.
It was built in the tenth century after the previous one was ransacked by Vikings.
At Hauptmarkt, you can savor traditional German cuisine at local cafés, shop for unique souvenirs, and absorb the lively ambiance of Trier’s historical center.
Stop 3: Trierer Dom (Trier Cathedral)
The Cathedral of Trier, or Trierer Dom, holds a weighty historical significance as Germany’s oldest bishop’s church, with roots extending back over 1700 years.
It was originally built by Constantine after he converted to Christianity. He built a complex of four basilicas where this stands now and, originally, it covered four times the area of what we see today!
Over time, it was changed and extended which lead to the blend of Romanesque, Gothic, and Baroque design elements that you’ll see today.
It houses an impressive collection of Christian relics, including the Holy Robe, believed to be the tunic of Christ.
The cathedral’s majestic interiors, intricate frescoes, and solemn atmosphere offer a journey through Christianity’s history in Europe, providing you with a reflective and awe-inspiring experience at this UNESCO listed site.
Stop 4: Liebfrauenkirche (Church of Our Lady)
Adjacent to the Trierer Dom, the Liebfrauenkirche is also a UNESCO World Heritage listed site and an example of early Gothic architecture with a unique circular design and an elegant rose window that casts ethereal light into its interior.
It was built on the remains of a church from Roman times with a circular building plan and 12 pillars representing the 12 Apostles. There are also circular portals and the whole design combines to form a 12 petalled rose outline which is a symbol of the Virgin Mary – who was known as the “Mystical Rose” at the time that this was built.
The architectural harmony and peaceful ambiance of the Liebfrauenkirche make it an essential stop for those interested in medieval religious architecture and the serenity it evokes.
Stop 5: Aula Palatina (Constantine’s Throne Room)
The Aula Palatina, or Konstantin Basilika, is a remarkable structure built in the early 4th century under Emperor Constantine as a part of his palace complex. At 71 metres long by 36 metres high and 32.6 metres wide, it’s the largest single room Roman structure still standing. It was built to express how important the Emperor was and it delivered.
UNESCO World Heritage listed, it has served time as an audience Hall for Emperor Constantine, a fortress, a residence for the Medieval Bishops of Trier and much more.
Today, it serves as a Protestant church. You can stand beneath its towering ceilings to fully appreciate the architectural prowess of Rome and the basilica’s historical significance as a symbol of the Roman Empire’s reach and influence.
It’s easy to walk here from the last stop and then onto the next stop.
Stop 6: Rheinisches Landesmuseum (Archaeological Museum)
This museum offers an in-depth exploration of Trier’s and the surrounding region’s rich history, and has the largest Roman collection in Germany.
Its extensive collection includes Roman mosaics, coins, relics and detailed models of the city at various points in its history. Through interactive exhibits and well-preserved antiquities, the museum covers what ordinary Roman life was like back then.
It also covers the history of Trier from before this period all the way through the Middle Ages to the Baroque.
Unfortunately, the museum is only in German so make sure you grab an English audio guide on entry.
Stop 7: Kaiserthermen (Imperial Baths)
Walk a little further and you’ll soon be at the Kaiserthermen, or Imperial Baths which is also UNESCO listed and built in the 4th century.
These are among the largest Roman bath complexes outside of Rome, showcasing the luxurious lifestyle of Roman elites and the advanced engineering of ancient Roman society.
You can explore the underground service tunnels, the remains of the hot baths, and the vast ruins of what was once a grand social and leisure center. You can even check out the size of the big hot water bath designed to hold 650 people for opera performances.
Stop 8: Amphitheater (Amphitheater)
Keep walking to Trier’s Amphitheater which is built into the hillside on the outskirts of the ancient city. It is a clear reminder of the Roman Empire’s entertainment culture, where gladiators and wild animals once entertained thousands of spectators.
It dates back to 100AD, could hold 20,000 spectators and is also UNESO listed.
Today, you can walk through the same entrances as the ancient Romans, stand in the central arena, and even explore the subterranean cells where animals and performers awaited their fate.
Stop 9: Barbarathermen (Barbara Baths)
About a 20 minute walk from the Amphitheater or a quick bus ride is the Barbara Baths. These are even bigger and older than the Kaiserthermen and were built in the second century. In fact, only baths in Rome were bigger than these in the Roman Empire.
Although less preserved than the Kaiserthermen, the ruins of the Barbara Baths still offer a glimpse into the complexity of Roman bath culture, with remnants of cold, tepid, and hot baths.
Information panels around the site help you understand the baths’ original layout and function, making it an intriguing visit for anyone interested in ancient Roman daily life.
Stop 10: Römerbrücke (Roman Bridge)
Your final UNESCO site for the day, the Römerbrücke stands as a testament to Roman engineering, being the oldest bridge in Germany still in use today.
Spanning the Moselle River, this ancient structure has been rebuilt several times but retains its Roman foundations with at least nine of the pillars still supporting the bridge being in action since the second century.
Walking across the bridge offers not only a connection to Trier’s Roman past but also provides picturesque views of the city and the river, making it an ideal stop for photography enthusiasts and history buffs alike.
OPTIONAL: Stop 11: Museum Karl-Marx-Haus (Karl Marx House)
This has been a huge day in Trier, but if you still have time and energy, there is somewhere else worth checking out.
The Karl Marx House was the birthplace of Karl Marx in 1818. It is now a museum dedicated to his life and works, offering an intriguing visit for those interested in the influences that shaped one of history’s most influential philosophers and social theorists.
The museum provides a comprehensive look at Marx’s personal history, his intellectual development, and his impact on political thought across the world. You can explore exhibits on Marxism, including manuscripts, personal belongings, and first editions of Marx’s works, providing a deep dive into the historical and social contexts of his theories.
