Trier Cathedral

Trier Cathedral (Trierer Dom) in Trier is considered the oldest cathedral in Germany and one of the most remarkable churches in Europe. Its fortress-like Romanesque walls hide masonry from the age of Emperor Constantine, and its story spans almost 1,700 years. Part of a UNESCO World Heritage Site together with Trier's Roman monuments, the cathedral also guards the Holy Robe, a relic believed to be the tunic of Christ. For anyone exploring the Moselle Valley, it is an essential stop.

A church older than Germany itself

Trier was one of the capitals of the late Roman Empire, known as Augusta Treverorum. Between 310 and 320, under Constantine the Great, a first church complex rose on this site, and around 340 a square central structure supported by four granite columns was added. Sections of that Roman-era masonry still stand inside today's building.

In the 11th century, Archbishop Poppo extended the cathedral westward from 1037, creating the massive west front you see on the square. The Gothic cloister followed between 1245 and 1270, and Baroque additions came in the early 18th century. The finished church is 112.5 meters (369 feet) long. In 1986, UNESCO listed it as part of the World Heritage Site "Roman Monuments, Cathedral of St. Peter and Church of Our Lady in Trier."

What to see inside

• The Holy Robe chapel: According to medieval tradition, Empress Helena, mother of Constantine, brought the robe to Trier. It is kept in a chapel behind the high altar and shown publicly only on rare occasions, most recently during the great pilgrimage of 2012.
• The west choir: A Romanesque apse crowned with ornate Baroque stucco.
• The "swallow's nest" organ: Built by Klais in 1974, it hangs from the nave wall and has 67 stops and roughly 5,600 pipes.
• The cloister: A peaceful Gothic courtyard linking the cathedral to the Church of Our Lady next door.
• The treasury: Highlights include the jeweled Egbert Shrine, a portable altar holding a relic of the Apostle Andrew, and the reliquary of the Holy Nail.

The adjoining Church of Our Lady (Liebfrauenkirche) is one of the earliest Gothic churches in Germany, so plan to see both.

How to get to Trier Cathedral

Trier sits in the far west of Germany, close to the Luxembourg border. From Trier Hauptbahnhof, the cathedral is about a 15-minute walk past the Porta Nigra. Regional trains connect Trier with Koblenz, Cologne, and Saarbrücken, and the Deutschlandticket is valid on these German regional routes. Luxembourg City is the nearest major city, and Frankfurt is roughly a three-hour journey by train, which makes Trier a long day trip but an excellent overnight stop. Prices are in euros (EUR).

Is it worth visiting?

Yes, especially if you're interested in Roman history or medieval architecture. Allow 45 to 60 minutes for the cathedral, cloister, and Church of Our Lady, and around two hours with the treasury or a tour. The main nave, aisles, and cloister are step-free, while the Holy Robe chapel and treasury can only be reached by stairs.
