In the rescue archaeological research in 2008 at the polycultural location in Obříství, in the northern part of communication No. 5, there were uncovered and documented eight graves from prehistoric times. Based on analysis of the tombs and findings situations, three graves can be classified into Late Neolithic Period, namely, 5th undecorated phase Stroked Pottery Culture.
Two graves were dated to the Early Bronze Age, specifically in the post- -classical phase Únětice Culture. Dating the remaining three graves is not possible due to the absence of culturally classified findings, two of the graves in this group could not be completely defined as graves.
Graves from the Late Neolithic Period may have a direct relationship to the settlements objects found at the site. The relationship between the burial ground and the settlement from the Early Bronze Age is so far failed to prove.
