The site no 7 at Piaski (Central Poland) was excavated in mid 1970's by R. Dragan as a part of archaeological rescue investigations on the area of the 'Piaski' open pit, the Belchatów Brown Coal Mine. The most of material obtained during the excavations comes from Neolithic, Early Bronze Age and Lusatian culture. Purpose of this paper is an analysis of two concentration of Early Bronze Age pottery fragments located in distance about 25 meters of each other consisting of respectively 8 and 197 potsherds. Dispersion of potsherds and a lack of the traces of stable settlement installations confirm that small and short occupation settlement of the Mierzanowice culture have existed here. A shape of vessels reconstructed on the base of fragments found during the excavations, ornamentation (horizontal impression of and double cord) and medium grain temper suggests are typical for early phases of Mierzanowice culture. The site at Piaski is one of above 200 sites of the Mierzanowice culture known from the area of central Poland.
