Trier, Germany has been settled since the 4th century BC, and for an extended period was a Roman settlement. As a result there are some fine examples of Roman architecture that remain in the city. While we were there primarily for the Rosenmontag parade, you can’t miss some of the other highlights of the town, including the ruins.
Unfortunately the baths were closed so we were unable to explore in any detail. I look forward to the day I can return and view the ruins properly.
