The Castle "Pf"alzer Schloss" in Gross-Umstadt is an aristocratic residence from a former moated castle. The moated castle was first mentioned in 1306 and served to secure the city at the southwestern end of the old city wall. In the 15th century it was converted into a castle. From the west side, you can see that the substructure has been integrated into the old city wall. The upper floor went through several construction phases.
