Castra of Irgenhausen, Roman fortification in Pfäffikon, Switzerland
The square-shaped Roman fort measures 60 meters on each side and features four corner towers along with three additional defensive structures.
Originally constructed between 294 and 375 CE, the fort protected a vital transportation route connecting Roman settlements at Kempraten, Oberwinterthur, and Eschenz.
The site preserves elements of Roman military architecture, including foundation walls measuring 1.4 meters in height and remnants of a three-room bathing facility.
Visitors can distinguish original Roman walls from modern restorations through a red line integrated into the structure's masonry during conservation work.
Archaeological excavations revealed a hypocaust heating system in the southern corner tower, connected to an earlier villa rustica from the 1st to 3rd century.
