Elephant Island contains one large cave. Elephanta Island is one of a number of islands in Mumbai Harbour, east of Mumbai. Known in ancient times as Gharapuri, the name Elephanta island was given by Portuguese explorers, after seeing a monolithic basalt sculpture of an elephant found near the entrance. The carvings narrate Hindu mythologies, with the large monolithic 20 feet Trimurti Sadashiva (three-faced Shiva), Nataraja (Lord of dance) and Yogishvara (Lord of Yoga) being the most celebrated.
