Bacho Kiro Cave (Bulgaria)

The Bacho Kiro cave (Bulgarian: пещера „Бачо Киро“) is situated 5 km (3.1 mi) west of the town Dryanovo, Bulgaria, only 300 m (980 ft) away from the Dryanovo Monastery. It is embedded in the canyons of the Andaka and Dryanovo River. It was opened in 1890 and the first recreational visitors entered the cave in 1938, two years before it was renamed in honor of Bulgarian National Revival leader, teacher and revolutionary Bacho Kiro. The cave is a four-storey labyrinth of galleries and corridors with a total length of 3,600 m (11,800 ft), 700 m (2,300 ft) of which are maintained for public access and equipped with electrical lights since 1964. An underground river has over time carved out the many galleries that contain countless stalactone, stalactite, and stalagmite speleothem formations of great beauty. Galleries and caverns of a 1,200 m (3,900 ft) long section have been musingly named as a popular description of this fairy-tale underground world. The formations succession: Bacho Kiro’s Throne, The Dwarfs, The Sleeping Princess, The Throne Hall, The Reception Hall, The Haidouti Meeting-Ground, The Fountain and the Sacrificial Altar.
