In addition to being India's largest and densest urban area, Mumbai is also the country's most populous city on the coast of Maharashtra. Mumba, a form of Parvati, one of Hinduism's most important deities, was the name given to the city after an ancient settlement on the site, whose temple once stood in the southeast corner of the city. In the colonial period, Bombay was known as Mumbai. During the period of British settlement, the name was possibly Anglicized from Bom Baim ("Good Harbour"), which is thought to be Portuguese. Despite the name Bombay's continued use in common usage, Mumbai was officially restored in 1995.
The long-established cotton textile industry of Mumbai gradually diversified into a highly diversified manufacturing sector with an increasing IT component. A strong and vigorous financial and commercial center, Mumbai is also a major financial hub of the country.
A peninsula, Mumbai is situated on Bombay Island, an island formed by seven islets off the Konkan coast of western India. As a result of drainage and reclamation projects, causeways, and breakwaters, the islets formed Bombay Island during the 17th century. Mumbai (Bombay) Harbour lies east of the island. In the east and west of the island, there are parallel ridges of low hills flanking a low-lying plain. About a quarter of the island is below sea level. A long ridge that forms the headland at Colaba Point protects Mumbai Harbor from the open sea. Malabar Hill, one of Mumbai's highest points, rises 180 feet (55 metres) above sea level. The shallow expanse of Back Bay lies between Colaba Point and Malabar Hill. The site of the British fortifications, within and around which the city grew in the 17th century, lies on a slightly raised strip between Back Bay and the harbour; today, it is largely occupied by public and commercial offices. The central plain extends northward from Back Bay. There is a large salt marsh in the extreme northern segment of Mumbai.
On the northern coast of Bombay Island, the old city stretches from Mahim and Sion to Colaba Point on the southern tip. A causeway connected Bombay Island to Salsette in 1950, allowing Mumbai to expand northward.
By 1957 a number of suburban municipal boroughs and some neighbouring villages on Salsette were incorporated into Greater Mumbai—the metropolitan region surrounding Bombay Island and the city itself. Since then Greater Mumbai has continued to expand.
