Mumbai lies on India's west coast in the state of Maharashtra facing the Arabian sea. The city  occupies an area of 440 sq km. One fourth of the city lies below sea level. The city is covered by two ridges of low hills on Colaba's east and west forming a barrier of sorts from the open sea .The other ridge ends up at Malabar Hill 180ft above sea level, which is also Mumbai's highest point. In between these two ridges directly north of Colaba lies the bustling area of fort.
          The buildings here are of British era and built in Gothic style. The two main stations VT (now known as CST) and Churchgate, the India Government Mint, the Reserve Bank, the General Post Office, the Bombay Stock Exchange, the Tourist office, private offices, banks etc.are all  located here. At the southern end is also Nariman Point, the land was reclaimed from the sea  to house the modern business center of Mumbai. Considered by many as "Manhattan" it has many high rise office buildings. To the north of the city are the two Airports, the International, the other Domestic. Mumbai's island location has constrained its ability to spread and grow over a wide area. Consequently high rise skyscrapers dominated the skyline until the city reached a saturated point. The idea of a twin city was mooted by the town planners. New Bombay lies to the north east of Bombay and covers an area of 345 sq km.
