Unusual Caves Around the World

Devetashka cave is one of the biggest caves in Bulgaria but it is most famous for its amazing history. It is also currently home to nearly 30,000 bats.


Devetashka cave is located 18 km (11mi)  northeast of Lovech and 2 kilometers (1.2mi) away from the village of Devetaki. The cave is also known as Maarata or Oknata for its seven different-sized holes in the ceiling, through which sunlight penetrates and illuminates the central hall and part of its two fields.


The entrance of the cave is 35 meters (115ft) wide and 30 meters (100ft) high. About 40 meters (130ft) after the entrance, the cave widens, forming a spacious hall with an area of 2,400 sqm (0.6 acres). The height of the hall is 60 meters (197ft); at some places it reaches 100 meters (330ft).
