Also known as the Pilės hillfort, Kepaluškalnis speaks to the fact that a castle or a hillfort were here in the past. The hillock has been dated to the beginnings of the 2nd millennium. Its size and its fortifications suggest that during the battles against Crusaders, this was one of the most fortified castles in Žemaitija. Indeed, it was the local centre for defence and administration. At the foot of the lake is a wooden monument that was installed in 1990. It honours Vytautas the Great and his victory in the battle of Žalgiris.
