The construction of the castle “Fridberch” was first mentioned around 1257 to secure the Wittelsbach borders. For a short time, the castle was repeatedly inhabited by high-ranking personalities due to its favorable location to Augsburg and was thus renamed a castle. After a fire in 1541, the castle was given a two-storey arcaded courtyard in Renaissance architecture; the arcades on the upper floor were walled up in the 18th century to improve the quality of living. The four-winged complex is surrounded by a moat. It is also home to the famous Köpfhäusl, a bastion tower next to which a place of execution was located.
