Mumbai is a singular urban entity, geographically born from seven volcanic islands that were painstakingly reclaimed and joined, creating the peninsula that defines its strategic coast. It stands as the undisputed Financial Capital of India, home to the country's central financial institutions (RBI, BSE) and responsible for over 6% of India's GDP and the majority of its maritime trade. This economic powerhouse is overlaid by a vibrant cultural legacy, characterized by its defining Victorian Gothic architecture, the unique logistical miracle of the Dabbawalas, and its status as the global epicenter of the Bollywood film industry—the world's largest by volume.
