Studies on anthropogenical transformation of soil within the grave-mound in Kolonia Kryłów (Hrubieszowska Basin) were carried out using pedological and archaeological methods. The soil on the top of grave-mound was classified as anthropogenic soil with initial features of lessivage processes. It is morphologically and chemically different from typical lessive soils (Haplic Luvisols) which occur in the immediate vicinity of grave-mound. In the anthropogenic soil, formed probably since Roman period, considerably changed some soil properties, such as humus content, reaction, enrichment in phosphorus. However, the lessive process is hardly advanced, probably because of, among others, relatively poor washing.
