The Western Area or Freetown Peninsula (formerly the Colony of Sierra Leone) is one of five principal divisions of Sierra Leone. It comprises the oldest city and national capital Freetown and its surrounding towns and countryside. It covers an area of 557 km2 and has a population of 1,447,271. The Western Area is located mostly around the peninsula and is divided into two districts: the Western Area Rural and the Western Area Urban.
Western Area is the wealthiest region of Sierra Leone, having the largest economy, the country's financial and cultural center, as well as the seat of the country's national government. Unlike the other regions in Sierra Leone, the western area is not a province.
It is divided into two districts:
Freetown serves as the administrative headquarters of both the Western Area and the Urban District, and served as the capital of the Rural District until 2009 when it was formally moved to the city of Waterloo.
To the northeast, the Western Area borders the North-Western Province, and to the southeast it borders the Southern Province. However, most of the boundaries of the Western Area is the shoreline of the Atlantic Ocean. The Western Area is the only region of Sierra Leone without a foreign border.
