The hillfort is located on a promontory of a highland, surrounded by Lake Žasliai from the southwest and an unnamed stream from the south. The triangular platform extends in a northwest-southeast direction, approximately 40 meters long and 50 meters wide at the northwest end. The northwest end likely had a rampart and a ditch, but these were destroyed during the construction of the Žasliai Church (the surface was cut down by about 1.5 meters). Only the southeast edge of the hillfort platform, which is 31 meters long and 27 meters wide at the northwest end, with a 0.6-meter
high and 13-meter wide dispersed rampart, has survived. This part of the hillfort is also significantly damaged by the chapel standing here and the graves around it. The slopes are steep, 10 meters high, with the southern slope eroding. In 1952, a cultural layer with charcoal, ash, and pottery shards was observed here.
The hillfort is dated to the 1st millennium - beginning of the 2nd millennium.
As late as the early 20th century, the hill on which the church stands was called Pajauta's Grave by the locals. To the northwest of the hillfort stands St. George's Church.
