The castle is built on the hill of Relong and dominates the scenery. A ditch and the outer enclosing wall delimit an area of 15,000 square metres. A second enclosure surrounds the buildings of the castle itself, placed against the northern wall of the outer enclosure. The circular keep of 32 metres is placed in an angle to the east of the inner enclosure, and is isolated from the castle itself by a wall. A narrow staircase is dug in the wall of the keep in order to reach the top, from where one obtains a panoramic view of surrounding country. The ruined buildings around the castle are still impressive: of particular note are the chapel windows on the northern side.
