Altes Schloss Kißlegg, Renaissance castle in Kißlegg, Germany

Altes Schloss Kißlegg is a three-storey square building with an asymmetrical stepped gable, built around 1560 on the site of a medieval castle. Three round towers with conical roofs stand at its southwest, southeast and northwest corners; the northeast tower holds a staircase. Inside, stucco by Antoni Frast dates from the 1717–1721 refurbishment, and wall frescoes with biblical scenes were uncovered in 1950 in one tower.

Hans Ulrich von Schellenberg built the castle in the second half of the 16th century as a sign of his rising importance. The property later passed to the Waldburg-Wolfegg family through marriage and remained in their hands for generations.

The castle has belonged to the Counts of Waldburg-Wolfegg since 1708, when it came to them through marriage; the family still owns it today. The interiors were refitted between 1717 and 1721 for Ferdinand Ludwig von Waldburg-Wolfegg and his wife Maria Anna, with stucco by Antoni Frast. In July 2016 the Denkmalstiftung Baden-Württemberg named it Monument of the Month.

The castle sits within the town and is visible from nearby streets, making it simple to locate. Access is available during certain events and conferences, so checking ahead about visiting hours and any restrictions helps plan your visit.

The Baden-Württemberg Monument Foundation named the Altes Schloss its Monument of the Month for July 2016, a designation that drew attention to the building's state of repair. The award recognised the castle's preservation as a whole, from its stepped gable to the stucco interiors of 1717 to 1721.
