Trier was a big deal for the Romans. In the 4th century, Trier was the imperial residence and all of the western part of the Roman Empire was administered from here. Here’s how big that empire was:
This is one of the Imperial Baths Constantine the Great had constructed here. Work on this project stopped when Constantine shifted his political activities to Istanbul in the east.
Today the site of these baths is a huge archaeological excavation project. You can walk in and around the structures and read about what it was like long ago. Most of the excavation took place after WWII, when buildings on this site were destroyed and excavation was possible.
We went underground to see the tunnels and the maintenance wing (service passages) where all the workers operated the heating systems for the baths. There were rows and rows of these tunnels underground, like mazes.
This tower was constructed to give a good view out over the bath complex. It was really remarkable. All this is located next to the palace quarter and the basilica. The visitor’s center had an animated film showing the development and use of the baths in this area. It was fascinating.
