Castra Batava

Castra Batava was a rectangular stone fortification located at the junction where the Danube and Inn rivers meet in Bavaria. The complex contained barracks, administrative structures, and defensive walls positioned to control this strategically important waterway location.

The fort was established in the 2nd century and took its name from the ninth Batavian cohort stationed there as part of Rome's frontier defense system. It served a key role in securing the eastern borders of the Roman provinces in this region.

The fort served as a meeting point where Roman soldiers and local peoples exchanged goods and ideas in everyday interactions. Visitors today can sense how different cultures came together and influenced each other at this location.

Archaeological remains of military equipment, tools, and pottery are visible at the excavation site from the Roman occupation period. Good walking shoes are recommended since the ruins spread across the terrain and ground conditions can vary with the season.

The fort operated in tandem with Boiodurum located across the river, forming a paired defense system. This arrangement of two fortifications working together controlled both water and land routes through the region.
