A Renaissance fortress with two prominent round towers on the sides of the entrance facade and a Gothic columned core. Next to the castle are the ruins of a Baroque granary, a smaller outbuilding and a garden from the beginning of the 19th century.
The castle has a central multi-storey residential tower, which represents the core and is also the oldest part of the building. The castle is four-winged and has two mighty square towers. The tower was fortified as early as the 14th century, later in 1537 and lastly after 1821.
The castle is interesting for its large wooden doors. They are made from a single piece of wood, which could only be shaped with an axe.
The door is supported by a thick pillar, and behind the door is a small dungeon. During World War II, many of the castle's frescoes were destroyed.
