Castra of Alteburg, Roman military fort in Idstein, Germany.
Castra of Alteburg is a second-century Roman military fort with a rectangular layout that follows standard Roman defense design. Today you can see foundation remnants that mark where the original walls, gates, and interior buildings once stood.
The fort was built in the second century as part of the border defense line between the Roman provinces of Upper Germany and Raetia. It was abandoned when Rome's frontiers shifted and the installation lost its military importance.
The name Alteburg reflects its history as an old fortified place, and artifacts found here reveal how Roman soldiers spent their daily lives within these walls. These objects show the routines and activities of troops stationed far from home.
The remains are accessible from outside and marked with information panels explaining the original layout and function. It is best visited on foot, as the ruins are spread across open ground and you need time to walk around and observe.
This was not just an isolated garrison but part of a network of signal towers that allowed Romans to relay messages quickly across large distances. These communication systems were crucial for coordinating defense along an enormous frontier line.
