Castra of Irgenhausen

Castra of Irgenhausen is a Roman fortified structure with a square layout and watchtowers at each corner. The ruins still display the foundation walls and remnants of bathing facilities that once served the garrison.

The fort was established in the late Roman period, roughly between 294 and 375 CE. It played an important role in protecting a major trade route connecting Roman settlements in the region.

The stone walls reveal how Roman soldiers lived and worked at this location. You can still see where they bathed and rested, giving insight into their daily routines.

The location sits in a rural area, so bring comfortable shoes and prepare for changing weather depending on the season. It helps to gather information beforehand, as access and available facilities may be limited.

Beneath the southeastern corner tower lies a Roman hypocaust heating system that once warmed the building. Even older are the remains of a villa rustica from the early centuries that sits buried beneath the fort itself.
