Devetashka Cave

The Devetashka cave is located 18 km northeast of Lovech and 2 kilometers from the village of Devetaki on the right bank of the river Osam. It is one of the largest caves in Bulgaria. It was discovered in 1921, and used as an oil reservoir in 1950.

The entrance of the cave is 35 meters wide and 30 meters high. About 40 meters after passing the entrance, the cave widens, forming a spacious hall with an area of 2,400 square meters. The height of the hall is 60 meters; at some places it reaches 100 meters.

It was shown in the 2011 action movie The Expendables 2.
