The capital city of the Indian state of Maharashtra, Mumbai (formerly Bombay), was the second most populous city in India, next to Delhi. Mumbai is home to three UNESCO World Heritage Sites: the Elephanta Caves, Chhatrapati Shivaji Maharaj Terminus, and the city's distinctive ensemble of Victorian and Art Deco buildings. It is the financial, commercial and entertainment capital of India, remaining as a relatively safe city for tourists and expatriates. It is also home to some of India's premier scientific and nuclear institutes. The city also houses India's Hindi (Bollywood) and Marathi cinema industries. Mumbai's business opportunities attract migrants from all over India.
