Saeva dupka cave, Show cave in Brestnitsa, Bulgaria
Saeva dupka is a show cave near Brestnitsa with five halls and several galleries. Its 205-metre length includes a river flowing 70 metres below ground, and the largest stalacton has a circumference of 60 metres. The cave lies at 520 metres above sea level and is about 3 million years old.
The cave shows evidence of continuous human presence from Roman times, with archaeological finds including Roman coins and pottery fragments. These discoveries indicate the site was used over many centuries.
The main hall is regularly used for choral performances and traditional Bulgarian music events because of its natural acoustic properties. The underground space creates a special setting for musical presentations.
The interior stays between 7 and 11 degrees Celsius year-round, so warm clothing is recommended for your visit. The guided tour lasts about 30 minutes and takes you through all the main chambers.
The cave's third chamber, Haramana, has such level ground and acoustics that Emil Dimitrov, Lili Ivanova, the Donbass miners' choir and the Bulgarian National Radio children's choir have performed there. Its helictites, resembling corals, grow sideways because air currents push dripping water off course.
