The Sаeva Dupka Cave is one of nine developed caves in Bulgaria. It is located near the village of Brestnitsa in the Lovech region. The cave’s name comes from the names of two brothers, Syu and Seyu, who hid in the cave during the time of Ottoman rule.
The cave opened for visitors in 1967, but was closed in 1990. It reopened in 2004. Sаeva Dupka consists of 5 galleries, the largest of which is The Srutishte (Demolished) Gallery. The gallery nearest the cave mouth is known as Kupena (Haysatck), since it resembles a haystack. Visitors then enter Strutishte, which looks like it has just been struck by a powerful earthquake, with stone blocks strewn on its floor. The galleries after that are called Harmana (Threshing Floor), Belya Zamak (White Palace), and Kosmos (Cosmos).
Sаeva Dupka is exceptionally beautiful, displaying all forms found in caves: stalactites, stalagmites, karst lakes, rock curtains, and so forth. The cave’s lavishly decorated walls and ceiling give visitors the impression that they have entered a cathedral. The Harmana Gallery has such excellent acoustic properties that concerts are held here that often feature large choirs and famous performers. The cave has also been used a setting in films.
