The High Castle in Fussen, which is often called the Castle of the Bishops, now houses a branch of the Bavarian State art collections (Bayerische Staatsgemäldesammlung). The gallery opened in 1977. Paintings of the late Gothic are on display in the Knights' Hall. A collection of Prince Oettingen-Wallerstein, which he sold to Ludwig I, was the basis of the collection. The Bavarian National Museum also provided sculptures by medieval masters of Swabia and the Allgäu region. The collection’s masterpieces are the painting "Savior of the World" painted at the end of the XV century, the altar of the first half of the XVI century, the panels of 1510 depicting Emperor Henry and his wife Kunigunda.
