The historic area of present-day Nowa Huta is one of the few places in Poland settled continuously since the neolithic age. Archaeological research has discovered a large Celtic settlement as well as Poland's oldest Slavic settlements in the area. In the 8th century, a mound was erected nearby by the Vistulans. According to legend, the "Wanda Mound" is a tomb of Wanda, daughter of Krakus, a mythical founder of Kraków. In the 13th century, a Cistercian monastery in the village of Mogiła was built.
