Oberstimm auxiliary fort

Oberstimm is a Roman auxiliary fort in Bavaria situated at the intersection of two major trade routes connecting the Alpine region to the Danube valley. The remains reveal the characteristic layout of a Roman military compound with stone foundations from its second construction phase.

The fortification was built between 45 and 50 AD as part of the Upper German-Raetian Limes, serving as a frontier defense. A second construction phase around 80 AD significantly expanded the compound to accommodate additional cavalry forces.

The name Oberstimm derives from the settlement that grew around this Roman outpost. Visitors can still trace the layout of the defensive structures that shaped how the Romans organized their frontier forces.

The site is easy to access on foot, as the stone foundations remain visible and clearly marked for visitors. Spring and autumn offer the best visiting conditions, with pleasant weather and good visibility of the remaining structures.

Excavations in the 1960s uncovered two Roman patrol boats now on display at the Roman and Celtic Museum in Manching. These discoveries reveal that the fort also functioned as a river station for controlling waterway traffic.
