The archaeological site Pločnik is a Neolithic place of the Vinča culture, and it is located in the village of Pločnik near the river Toplica and Prokuplje. This Neolithic settlement was found in 1927 while tracing the railway Prokuplje-Kursumlija. This settlement consisted of several units and its habitants were mainly engaged in agriculture.

Stone was the basic material for making tools.  A lot of ceramic vessels were found here as well as tools and objects made of copper. Two ground furnaces were also found which were used for melting metals. Based on this, it is claimed that Pločnik is the oldest center of metallurgy in Europe from 5300 to 4600 BC.
