Tell Yunatsite, also known as Ploskata mogila, is situated in the Pazardzhik Province of southern Bulgaria, some 8 kilometres (5 mi) to the west of the district capital Pazardzhik. The tell stands 12 metres (39 ft) above modern ground level and has a diameter of 110 m (360 ft). It is situated on a low terrace at the right bank of the former Topolnitsa riverbed near to its confluence with the Maritsa River. Medieval, Roman, Iron Age, Early Bronze Age, and Copper Age periods have all been attested at the site. The Copper Age tell is associated with the Karanovo culture.

The Karanovo culture is a Neolithic culture named after the Bulgarian village of Karanovo. The culture, which is part of the Danube civilization, is considered the largest and most important of the Azmak River Valley agrarian settlements.
