Trier Imperial Baths Historical Timeline

Known as the “Kaiserthermen”, the Imperial Baths at Trier are one of the finest examples of a Roman bathing complex. The baths were commissioned by Emperor Constantine the Great as part of a new Imperial palatial complex that he wanted to build in the city.

Trier had been one of Rome's most important cities in Germany for centuries and was known as Augusta Treverorum. As ruler of the Western Empire, Constantine would use Trier as one of his residences.

Work initially began in 306 AD but ceased during the 3rd Century AD. The program was restarted in the 4th Century and finally finished. The complex also contained a barracks for the Emperor's Imperial guards.
