On the outskirts of the Petrachos hill below the Acropolis and near the Archaeological Museum is the Ancient Theater of Cheronia. Its first construction dates back to the end of the 5th century BC. It is perfectly integrated into the site, since it was carved into the natural rock of the elevation and could accommodate about 500 spectators.Only the carved into the rock part of the theater is preserved.

During the Roman period, several works were carried out which increased the capacity of the theater and slightly modified its appearance.

At the entrance to the archaeological site there is a stone-built fountain, built in 1865 with embedded ancient material.
