The small, former hill castle site is located in the Franconian Switzerland-Veldenstein Forest Nature Park, about 850 metres west-northwest of the church in Affalterthal at a height of 458.9 m above sea level (NN) on the summit of the Altschlossberg,[1] about 15 kilometres east of Forchheim.

On its northwestern and northeastern sides the spur is bounded by the valley of the Brunnengraben, where the steep drop of the hillside ensured that the castle was naturally well protected.

On the northeastern side are two stone ramparts that run parallel to the edge of the plateau and which are separated by a roughly two-metre-wide and one-metre-deep ditch.

In the west, in addition to the stone ramparts, is a round, two-metre-deep hollow, that is probably the cellar of a castle building.

Immediately next to it are the remains of a rectangular foundation wall about 3 and 1.8 metres long, consisting of ashlar-shaped, rough-hewn stones.
