The Central Area, also called the City Area, and informally The City, is the main commercial and financial city centre of Singapore. Located in the south-eastern part of the Central Region, the Central Area consists of eleven constituent planning areas: the Downtown Core, Marina East, Marina South, the Museum Planning Area, Newton, Orchard, Outram, River Valley, Rochor, the Singapore River and Straits View, as defined by the Urban Redevelopment Authority. The term Central Business District (CBD) has also been used to describe most of the Central Area as well, although its boundaries lie within the Downtown Core.
Singapore's modern history began in this area, when British colonial official Stamford Raffles and representatives of the British East India Company landed along the banks of the Singapore River in 1819 to set up a free port of trade between Europe and Asia. As the old harbour grew along the mouth of the river bank, the historical city naturally expanded around it, creating what is now the Central Area. As the financial heart of Singapore, the Downtown Core also houses the headquarters and offices of numerous major corporations, both local and international, as well as the Singapore Exchange (SGX). As the country's de facto capital, it is also home to many governmental institutions, most notably the seat of Parliament and the Supreme Court.
