Castra of Osterburken

The Castra of Osterburken is an ancient Roman fort with preserved stone foundations, ditches, and wall sections standing at 256 meters elevation along the frontier. The site features a double fort layout with a main fort and an attached annex fort, both showing clear structural remains.

The fort was built in the 2nd century as a military garrison in Germania Superior to defend the empire's northern frontier. It formed part of the Limes defense system that stretched across the region.

The fort reveals how Roman soldiers built their structures through visible walls and foundations scattered across the site. Walking through, you notice the careful layout that helped soldiers organize their daily lives and defense routines.

The archaeological site is walkable, with a reconstructed Roman watchtower and information panels about soldier life spread across the landscape. The Limes Park grounds are easy to navigate, with markers and displays helping you understand the layout and key areas.

The double fort configuration with a main garrison and attached annex is unusual and shows how Romans sometimes staggered complex defense structures. This particular setup makes Osterburken stand apart from other Limes forts.
