Cave of Kapsia, Show cave and archaeological site near Tripoli, Arcadia, Greece.

Cave of Kapsia is a natural show cave featuring a large main chamber with stalactites and stalagmites in varied colors throughout its passages. The interior consists of multiple connected rooms that display the geological formations created over millennia.

The cave was discovered in 1887 during investigations of the ancient city of Mantineia. Archaeological excavations later revealed that people inhabited and used the cave during the ancient Greek period.

The cave served as a refuge for ancient peoples who left traces of their daily life within its chambers. Today visitors can observe how communities once used this natural shelter for protection and dwelling.

Wear comfortable shoes and bring a jacket since the cave interior stays cool and damp throughout the year. The pathways inside are sometimes slippery, so take care especially on the stairs and steep sections.

The cave lies in the closed basin of the Mantineian plateau and connects to a network of natural sinkholes feeding the local aquifer, so its water does not run to the sea. Finds inside include human bones and everyday clay vessels, alongside lamps, tools and cave-cricket remains.
