The fish mound dates back to the 1st millennium. vid. - II thousand. pr. and is one of the earliest in the municipality, also known as Ąžuolynas Hill. 1971 the mound was explored by the Institute of History. The fish mound contains molded pottery on a level surface and surrounded by pottery.
The finds are kept in the Museum of History and Ethnography. The mound is heavily destroyed by plowing, now it is soiled, and the site and slopes are overgrown with alder.
The site is quadrangular, elongated in the NE-SE direction, measuring 22 × 18 m, 2 m lower in the north-western part. A 1 m high, 12 m wide embankment has been poured on its northern edge. At the south-eastern foot there was a ditch and an 8 m wide, up to 1 m high embankment (destroyed, the remaining 13 m wide plane, the remains of the embankment are visible on the slope to Vuolasta). The slopes are steep, 4.5–20 m high. There is a cultural layer on the P slope where smooth and ringed pottery is found.
