The article presents the results of archaeological excavations carried out in relation to the construction of the Wieluń bypass (sites 6 and 8). In 2007-2008, traces of settlement were discovered here from the Stone Age (Mesolithic), Bronze Age, Hallstatt period, Roman period and the early modern period. Surface investigations distinguished two sites: 7 and 8, which turned out to be one during the excavations. The works supplied extremely abundant relic material in the amount of 18 892 pieces primarily ceramic material – 17 493 fragments, accompanied by flint artefacts, pugging, metal relics (axe of the Lusatian culture, clasp of the Roman period, iron knives), jointers and hammerstones, as well as burnt animal bones.
