Mumbai, originally a collection of seven islands inhabited by local fishing communities, was ceded to the British by Portugal in 1661. Notably, it is home to significant landmarks such as the Victoria Terminus, now Chhatrapati Shivaji Terminus, and the Gateway of India, which commemorates the British royal visit in 1911. Today, Mumbai is India's most populous city, a cultural hub, and ranks as the fourth most populated city in the world.
