The oldest section from the 12th century was supplemented by a 2-story bailey that is protected by two moats.

The castle was remodeled and expanded, mixing the medieval style with Renaissance elements.

The southwest corner with the Chapel of Saint Pancras constitutes the oldest section of the castle.

The frescoes from the second half of the 14th century show St. Alfa, St. James the Elder, the Martyrs of Ten Thousand, St. George, and the Caravan of the Three Kings.

Two stone figures, St. Anna and St. John Nepomuk, originally from Schloss Wieden at Kapfenberg, also stand along the access road.
