On our way home from a trip to Luxembourg City last weekend (to be discussed in a later post), Brian and I decided to take a side trip to Trier, which really couldn’t have been more “on the way.” Trier is located in Western Germany, just 40 minutes by car from Luxembourg City.
I didn’t know this, but Trier is historically in English called Treves, and it’s the oldest city in Germany, founded in or before 16 BC. You know it’s pretty old when it’s older than my dad. 🙂 (JUST KIDDING! That was just a special shout out for your birthday. I love you!)
Trier is a small city of about 100,000 people (making it less than half the size of Freiburg), but it’s amazing history rivals that of any location I’ve seen to date. We took a self-guided walking tour (which is where all of this educational information in the captions came from) on a beautiful day and got some amazing photos!

House of the Three Magi (Dreikönigenhaus) – One of the oldest stone houses in Germany, built in 1230.

Porta Nigra (Black Gate). Fair warning, I took a bajillion pictures of this. It’s the largest surviving Roman city gate worldwide. The gate was built sometime between 160 and 200 AD. It was converted into a church in the 1000s, and remained so until the 1800s.

Der Dom, also known as the Trier Cathedral. Originally, this was about four times as big as the church from around 300 AD.

Der Dom on the left, and the Church of Our Lady on the right. COL is the oldest Gothic church in Germany, dating back to the 1200s.

View of Electoral Palace and the Imperial Throne Room (larger brown building behind it.) The Imperial Throne Room is the largest surviving single room from Antiquity. It was built around 310 AD, and today is a Protestant Church.
