Ajanta Caves are about 30 caves located in the Indian state of Maharashtra. With Ellora Caves, they are among the most-visited sites in India. The Ajanta Caves have been made an UNESCO World Heritage site in 1983. They are located in a valley, about from the town of Ajanta, in the northwest of the state. Buddhist monks lived in the valley, from 2nd century BCE to about the 7th century CE. They used some of the caves to make temples. All the caves are located near a non- perennial river, which only has water during and shortly after Monsoon season. Most of the caves were also used for being lived in. Only four are designed to be temples . The most important caves also contain paintings.
