Mindelburg

Mindelburg Above the Mindeltal lies Mindelburg, southwest of the city. With fortified round bastions, gates and ditches, it meets the requirements of a medieval castle. The oldest parts visible today indicate the founding of a castle in the late 12th century. Among other things, the castle was the seat of the Dukes of Teck and the family of Frundsberg. In the built in 1370 and 1718 baroque St. George's Chapel is the oldest late Gothic Madonna of the city (1490). In the vaulted drinking room in the Benefiziatenhaus a mural from the period around 1520 is preserved, showing the lord George I von Frundsberg with guests. Parts of the castle are rented.
The castle courtyard with the 27-meter-deep castle fountain is accessible year-round, the castle keep converted into an observation tower from May to October, as part of guided tours as well
the chapel. Burggaststätte in the outer bailey (Tue day of rest).

On the western ridge above the Mindeltal lies southwest of the city, the extensive complex of Mindelburg. It was once the seat of the dukes of Teck and the family of Frundsberg, whose most famous member was George I. von Frundsberg. The oldest visible components indicate a castle founding in the late 12th century probably to secure the coming from Munich via Landsberg and until at the Bodensee continuing salt and trade route.

The castle was probably built in the second half of the 12th century on the Georgenberg. In 1305 it was destroyed and rebuilt in 1370 under Duke Friedrich von Teck.
