Burg Hohenschelklingen, Mountain castle in Schelklingen, Germany.

Burg Hohenschelklingen is a hilltop fortress near Schelklingen with a medieval defensive tower as its main remaining structure. The preserved walls show a square layout and thick stone construction typical of fortifications from that era.

First documented in 1127 as Castro et villae Schälkalingen, the castle passed through the marriage of Adelheid von Schelklingen to Count Heinrich von Berg around 1200. Around 1265 the bergfried was built in its present form. In 1343 Count Konrad sold town and castle to the Austrian dukes; in 1633 it was destroyed and from 1650 to 1653 demolished, its stones used for the Franciscan monastery in Ehingen.

The castle's name comes from the noble family who ruled the area and left their mark on the region for generations. The remaining tower displays the thick stone construction that defined fortress building in medieval Swabia.

The tower is open for visits during the summer months from May through September on specific weekend days with afternoon hours. Wear sturdy shoes since the paths leading up to the hilltop can be steep and uneven.

The 22-metre bergfried, also called Schlossturm, can be climbed as a viewing tower on certain days; it was cleared of rubble and given an interior staircase during the 1896 restoration by the town and the Schwäbischer Albverein. The castle was demolished from 1650 to 1653, and its stones were used to build the Franciscan monastery in Ehingen.
