Things to See in Trier Germany- Trier Roman Ruins and MORE

A few years ago I had the chance to spend a week in the Mosel River Valley and was able to enjoy some time in Trier. It’s one of the oldest cities in Germany and loaded with history. Since it is also pedestrian-friendly, our family was able to explore much of it on foot, and the kids were excited to visit the Trier Roman Ruins, the Dom and the Historical Museum …especially since there are also LOADS of Eis/Ice Cream stands along the way! Nothing motivates an 8-year-old like an Eis zum mitnehmen (ice cream cone to take along). There are so many things to see in Trier Germany! It is well worth a visit.

There really is a lot to see in Trier, Germany… but I think it might be best to start with a little background information about the city, to put it all in context.

History of Trier, Germany

Porta Nigra  

If you want to explore ancient Roman ruins, stand in a gladiator arena, or visit a Roman emperor’s fortress, then you might want to start planning a vacation to Rome, right? Well, not necessarily. If you are heading to northern Europe, or Germany in particular, then there is a great destination you can visit that is sure to satisfy even the most avid historical curiosity of the ancient Roman Empire.

One of the oldest settlements in Germany is the city of Trier, whose history can be traced back to when Germany was a part of the Roman Empire’s far reaching frontier. Trier, which sits behind the Roman Limes (Roman borders, see more here), contains more Roman ruins than any other city north of the Swiss Alps and was designated as a United Nations World Heritage site in 1986. 

The area that would become Trier was occupied by the Romans in 16 B.C. and was known as Augusta Treverorum which means “city of Augustus in the land of Treveri.” During the third century A.D., Trier was established as the capital of the Western Roman Empire, and from 293-395 A.D. was among the residences of the emperor. Between 306 and 337 A.D., during the reign of Constantine the Great, Trier was rebuilt, along with the construction of other Roman buildings such as the Palastaula and the Imperial Baths. In 326, sections of the imperial family’s residential palaces were transformed into a large basilica which is still partially visible in the vicinity of the cathedral. The Romans heavily influenced the wine growing in the Mosel River Valley, which is why those green stemmed German Wine glasses from the region are called Roemer Glass (Roman Glass).

The borders of the Roman Empire, the Roman Limes, are still visible in many places today.

The Roman army eventually withdrew from Trier during the fifth century and the city was sacked repeatedly by the Franks, as well as warriors belonging to the infamous Atilla the Hun in 451 A.D.

The city survived and even thrived again up until the fourteenth century when it became home to the prince-electors, or those princes who were loyal to the Holy Roman Emperor.

Trier was briefly under the authority of France early in the nineteenth century and then by Prussia in 1815. One of the city’s most famous citizens, Karl Marx, the father of communism, was born there in 1818.

Today, Trier boasts a population of around 100,000 people, and is home to a university. It is also one of the most popular tourist stops in Central Europe. This magnificent city is situated on the Mosel River and is surrounded by the scenic Eifel and Hunsruck Mountains. It is a mere six miles from the Luxembourg border and is centrally located for excursions into Luxembourg, the Mosel vineyards and the beautiful mountains surrounding the city.

Porta Nigra

The Porta Nigra, or “Black Gate,” is a huge second century gate that was once a part of the city’s wall system. It was constructed out of red sandstone and it is called “Black Gate” because of its dark appearance resulting from years of accumulated soot and dirt. Two towers and a courtyard accompany the gate, and in the eleventh century it was made into a church, St. Simeon, where parts of the church decorations can still be seen inside.

The Stadtmuseum Simeonstift is located adjacent to the Porta Nigra and focuses on regional history with an emphasis on art and artifacts from the Middle Ages forward.

Römische Palastaula

The Römische Palastaula is a huge, 220-foot long, 90-foot wide, 118-foot high fourth century basilica that was once the throne room of the Roman emperor Constantine. It is the larges surviving single-room Roman building. During the middle ages it was part of the prince-electors residence. It has been used as a Protestant church since the nineteenth century.

Have the energy for one more church? It might help to stop for another Eis or a Kaffee first…The Church of St. Gangolf, just off of the Hauptmarkt, was the site of the Protestant opposition to the Catholic cathedral. It is entered by going through a small flowery gate on the south side of the market square. The church is the second oldest church in Trier.

Birthplace of Karl Marx

The birthplace of Karl Marx is now a museum dedicated to the founder of communism. Marx only lived there for the first year of his life before moving with his family to a house near the Porta Nigra. The new residence where Marx lived until he went off to university can be located by a plaque marking the house. Recently, there has been some controversy because the Chinese donated a statue of Marx to the city of Trier.. (read more here–> Karl Marx Statue)
