Mindelburg

On the western ridge above the Mindeltal is the extensive Mindelburg complex southwest of the city. It was once the seat of the Dukes of Teck and the von Frundsberg family, whose best-known member was Georg I von Frundsberg. The oldest components visible today point to the foundation of a castle in the late 12th century, probably to secure the salt and trade route coming from Munich via Landsberg and continuing to Lake Constance.

Mindelburg Over the Mindeltal lies the Mindelburg southwest of the city. With defensive round bastions, gates and ditches, it corresponds to the ideas of a medieval castle. The oldest parts visible today point to the foundation of a castle in the late 12th century. Among other things, the castle was the seat of the Dukes of Teck and the von Frundsberg family. The oldest late Gothic Madonna in the city (around 1490) is in the St. George's chapel, built around 1370 and baroque in 1718. In the vaulted drinking room in the Benefiziatenhaus there is a wall painting from around 1520, which shows the lord of the castle Georg I von Frundsberg with guests. Parts of the castle are rented.
