The article has the aim to reveal the importance of hunting for the Lithuanian people’s everyday life in Southeastern region in the 13th – 14th centuries. This aim was achieved on the basis of the palaezoological data accumulated due to the archaeological researches of the bone relicts found in the archaeological monuments of Southeastern Lithuania. The article reveals that hunting was viewed differently by ordinary members of the community and the ruling elite. For the nobility, hunting, especially of big game, was a pleasant activity, and the hunted meat enriched their feasts. The commoners, however, used the meat of domesticated animals. European bison, aurochs, elks, and wild boars were among the most frequently hunted game. Beavers, as hunting objects, were also popular. In addition, some part of the population was obliged to hunt a certain amount of fur-bearing animals and to produce a certain amount of fur. The bones and horns were used by many craftsmen. Also, written sources give evidence about the existence of medieval hunting castles in Southeastern Lithuania. In this respect, the analysis of the data of palaezoological material gives some hope to locate one more of such hunting castles which could have been built on the mound of Bradeliškiai.
