The area of distribution of archaeological sites of the East Lithuanian Barrow Culture covers the territory of eastern Lithuania and the adjacent north-western regions of Belarus. However, over a long period, starting from the second half of the 20th century, there has been an obvious unbalance in the degree of study of the antiquities of this culture in the territory of Lithuania and Belarus. Belarusian part of the area is significantly less studied. This concerns both field research and the publication of archival materials and museum collections. For this reason, the eastern and south-eastern part of the area of the culture is perceived by many researchers as an understudied and poorly outlined periphery. The main task of the paper is to systematise the available information on the topography and chronology of the East Lithuanian Barrows in the territory of north-western Belarus and to determine the eastern and south-eastern borders of the culture as precisely as possible.
