Schloss Randegg, Medieval castle in Gottmadingen, Germany.

Schloss Randegg is a three-story stone castle located on a hilltop at the western edge of Gottmadingen, featuring three corner towers and a mansard roof. The structure combines medieval elements with later additions that shape its overall appearance.

The castle was first documented in 1214 and suffered severe destruction during its history, particularly in 1639 when Swedish troops attacked during the Thirty Years' War. After this assault, it was later rebuilt and continued to change over subsequent centuries.

The castle hosts the "Experimentelle" art exhibition every two years, a series running since 1989. The chapel, built in 1592 by Hans von Schellenberg, holds glass paintings designed by Otto Dix in 1963. The Knights' Hall was painted during the renovation after 1899.

The castle is privately owned and cannot be visited on a regular basis. The biennial art exhibition "Experimentelle" has been held there since 1989. The site lies on a hilltop at the western edge of the village, surrounded by a ring wall.

The chapel that holds Otto Dix's 1963 stained-glass windows was built in 1592 by Hans von Schellenberg. Dix lived in the castle from 1933 to 1936, and his windows were installed more than 25 years later.
