Dom St. Peter

Die Hohe Domkirche St. Peter zu Trier ist die älteste Bischofskirche Deutschlands uind recht eigenwillig. Seit 1986 ist der Trierer Dom Teil des UNESCO-​Welterbes. Sehenswert.

It is the oldest cathedral in the country. The edifice is notable for its extremely long life span under multiple different eras each contributing some elements to its design, including the center of the main chapel being made of Roman brick laid under the direction of Saint Helen, resulting in a cathedral added onto gradually rather than rebuilt in different eras.
In 1986 it was listed as part of the Roman Monuments, Cathedral of St. Peter and Church of Our Lady in Trier UNESCO World Heritage Site. If you like old churches and interesting buildings from the roman era, you must visit this place.
I think it is beautiful and quite artistic and different to the cathedrals you see around Germany.

Very ornate church. Lots to look at here the day we were visiting they were playing the pipe organ –very loud and «stern» sounding –just really wanted to be at a hockey game while listening. Worth the visit.

There’s not much I can add to Michelle’s review; she did an impressive job.
There are some neat things to see here: for example, the «L» in the platz in front of it marks how far it used to stand. The cathedral was 4 times larger than it is now. The dom is attached to the Liebfrau Church, which was built in a Romanesque style. Admission is free, and yes you can take pictures. The span of centuries is amazing to us Americans who have by comparison such a young country.

I know what many people think about Europe: You’ve seen one church and you’ve seen them all. Yet by skipping this one, you’re missing out on quite a bit more. Religious or not, the history behind this cathedral is astounding. Is that really a piece of Christ’s robe? The nail used on the cross? Or simply imagining how this church has been standing for nearly 1800 years. That’s right, 1800 years. Granted only part of the church from Emperor Constantine’s era still stands, but you can still set foot among the old stones. Even the expansion is almost 1000 years old, a rather impressive feat when you think about it. In fact, it’s the oldest church in Germany, so there’s plenty of history to be found here.
One could spend a while in here exploring, walking up and down the aisles, into the courtyards, through the treasury. There’s so much you can walk through, but be mindful — this is a church, so respectful clothing is a must and it’s an active Catholic church. Great if you want to attend a service, not so much if you show up during Mass trying to see the interior only.
It’s a church not to be missed for history buffs and religious people alike.
