Alte Burg Battenberg, Medieval spur castle in Battenberg, Germany.

Alte Burg Battenberg was a spur castle on a northeastern spur of the Kellerberg at 355 meters, above the Eder valley. Its oval complex had a three-story manor house, a ring wall, and a shield wall with a gate tower. The manor was demolished around 1740; today only a cellar vault and part of the ring wall remain, bordering the Neuburg courtyard.

The fortress was first documented in 1214 and came under the control of the Counts of Wittgenstein after they acquired the neighboring Battenberg county. This change of ownership shaped the political structure of the region for centuries to come.

The name Alte Burg (Old Castle) dates from 1732, when the new hunting lodge, the Neuburg, was built just southwest of it. The castle church parson lived in the old buildings until they were sold to the Protestant parish in 1779 and demolished. The parish and community house at Hauptstraße 65 now stands on the site.

The site sits on elevated terrain with good views over the surrounding landscape, making it worth a visit for a walk. Visitors should be prepared for uneven ground since the castle location is on a steep spur of the mountain.

A deep neck ditch protected the castle from the Kellerberg side, while a tall shield wall and high gate tower formed its primary defensive structures. These combinations of ditch and walls show the sophisticated defensive strategy typical of castles from that period.
