Saeva Dupka Cave’s five halls and 400 metres of corridors offer some of the most beautiful cave formations in the country. The cave has hosted many choral music performances, thanks to the excellent acoustic conditions. Saeva dupka was named after two brothers, Seyu and Sae, who used it as a hiding place during the Ottoman occupation of Bulgaria. Recent excavations have shown the cave was inhabited since Roman times. Saeva dupka is one of the 100 Tourist Sites of Bulgaria.

This stunning natural cave is like a temple and several films have been shot there.
