The 1st millennium hillfort and settlement on Lake Lapainia

Palapainės piliakalnis su gyvenviete, also known as Vilūnai or Lapainia, is a unique archaeological site and hillfort located in the Kaišadorių district. The fortification was built on a narrow headland on the left shore of Lake Lapainia. While the lake flooded a long north-south clearing during the 19th and early 20th centuries, a portion of the southern side remains visible. This includes a rampart measuring 17 meters long, 5 meters high, and 12 meters wide, followed by a 13-meter wide trench that is 1 meter deep. The slopes of the hill reach a height of 15 meters.

Archaeological research on the site began in 1943 by Petras Tarasenka, with further investigations conducted by the Institute of History in 1953 and 1971. The hillfort is dated to the 1st millennium and the beginning of the 2nd millennium. In 2008, further archaeological studies identified a settlement at the foot of the hill on a 1.3-hectare area, where researchers found both coarse and fine ceramics.

To preserve the site, the crumbling slopes of the hillfort were reinforced with stone bundles in 1994. The site was officially declared a cultural monument by a Lithuanian Republic Government resolution on May 19, 1998. The protected territory covers an area of 17,400 square meters. It is located off the road between Kruonis and Jieznas, reachable by turning toward Migonis and following specific directions toward Purvininkai.
