Colaba is a part of the city of Mumbai, India, and also a Lok Sabha constituency. During Portuguese rule in the 16th century, the island was known as Candil. After the British took over the island in the late 17th century, it was known as Colio. The name Colaba, comes from Kolabhat, a word in the language of Kolis, the indigenous inhabitants of the islands, before the arrival of Portuguese. The Island was one of the 7 that was land reclaimed to become Mumbai (Bombay).
