The Ajanta Caves are cut into a forested, crescent-shaped ravine lining the river Waghur. Dating from about 200 BC to AD 650, the caves were lost for centuries and discovered by British army officers in 1819 while tiger hunting. Twenty-eight caves are chiselled out of the brown cliffs. Inside the caves are rows of stone Buddhas and other sculptures. The interior surfaces of the caves are covered with murals depicting everything from battles, cities, and animals.
