Over two thousand years ago, Mumbai was an archipelago of seven islands, inhabited by the kolis. These tribal fisherfolk still live here in tightly knit communities that the passing centuries have scarcely touched. The best place to see them is in the 600-year-old Worli Fishing Village that stands on a sliver of land jutting into the sea. Plunge into one of its winding gullies and you will instantly be assailed by the smell of drying fish, and colourful koli women, their dark skins offset by chunky tribal jewellery. At the end of the village is a small Portuguese fort with remnants of an old armoury, soldiers' barracks and thick ramparts. Before the Raj, when Portugal ruled Mumbai, this was a strategic vantage point to counter attacks from the sea.
