🧿 Trier Imperial Baths

The Trier Imperial Baths are a large Roman bath complex in Trier, Germany. The complex was constructed in the early 4th century AD, during the reign of Constantine I. During that time, Trier was a major imperial hub, being a primary residence for Constantine's son Crispus. The baths were built around hot water pools reaching 40°C. Underneath the complex was a network of underground passageways used by the staff which can still be seen today, along with the remains of the sewer system. However, the baths were never completed and were made into a castle in the Middle Ages.
