The Kanheri Caves are a group of caves and rock-cut monuments formed from a massive basalt outcrop in the forests of the Sanjay Gandhi National Park, on the western outskirts of Mumbai, India. They contain Buddhist sculptures and relief carvings, paintings and inscriptions, dating from the 1st century BCE to the 10th century CE. Kanheri comes from the Sanskrit Krishnagiri, which means black mountain.
