There once stood a mighty castle on this hill, no excavations have been made here so very little is known about the ruin. Lots of ornamented bricks is scattered throughout the area.
There is a castle ruin just to the right just outside of this picture. My friend took a photo of me standing on the remains of a wall from that castle ruin. http://s.agirshus.com/Bilder/Annat/Utflykter/20090719_cykeltur/DSC_6578.jpg
