There used to be about a dozen mounds here, but most of them were destroyed when they built the railroad. There´s also an 8-stone square.

To the north you see the walls of Halleberg. They are this steep all around the hill, except for at one place - where the road from Vargön climbs the hill. Almost on the top, you can see the walls of a prehistoric fort (400-600 AD), guarding the only entrance - the one you´ve just been driving through - the rest of the hill needs no defence....
