Obětní kámen is an unusual weathered rock situated on a sandstone outcrop close to Mužský, in the Příhrazské skály rock area. The site has clearly seen human activity over a long period, possibly since the Neolithic and Bronze Age periods when the Mužský plateau was occupied by settlers, particularly at the Hrada hillfort.

How the stone was used remains a mystery, but it may have had a ritual purpose. There are small rock caverns immediately next to the stone.

To reach the site requires taking a small (marked) diversion off the blue hiking trail to the south of Mužský hill.
