Burg Sulzburg, Medieval castle ruins in Unterlenningen, Germany
Burg Sulzburg is a medieval castle ruin perched on a basalt tuff hill near Unterlenningen. The site displays a rectangular layout with an outer bailey and a shield wall, with the structures still clearly visible today.
This fortress was first documented in 1335 and belonged to the Lords of Neidlingen. Imperial forces destroyed it during the Thirty Years War, after which it fell into ruin.

The site contains remnants of two palaces from different periods with varying dimensions. This discovery reveals that the fortress was expanded and rebuilt over centuries, a process still visible in the foundations today.
