The Bėčionys Mound was first studied in the middle of the last century by the Institute of History. At that time, archaeologists discovered a cultural layer and pottery with a striped and smooth surface on the mound site.
Recent archaeological investigations have unearthed a number of finds, including traditional and black Gothic pottery, a belt sherd, a complete shattered pot with a striated pottery rim and other small fragments of pottery (1st-4th century). A thinner or thicker cultural layer is recorded in the mound (2nd-1st century BC – 1st-3rd century AD).
