The Gateway of India is a monument built during the British Raj in Mumbai City of Maharashtra state in Western India . It is located on the waterfront in the Apollo Bunder area in South Mumbai and overlooks the Arabian Sea. The structure is a basalt arch, 26 metres (85 feet) high. It lies at the end of Chhatrapati Shivaji Marg at the water's edge in Mumbai Harbour. It was a crude jetty used by the fishing community which was later renovated and used as a landing place for British governors and other prominent people. In earlier times, it would have been the first structure that visitors arriving by boat in Mumbai would have seen.
