St. Mary's Island (Gambia)

Weather…

St. Mary's Island, primarily known today as the location of the capital city Banjul, sits at the confluence of the Gambia River and the Atlantic Ocean. The island was settled by the British in 1816 under the command of Alexander Grant to serve as a military outpost to suppress the illegal slave trade. Originally called Banjul, it was renamed St. Mary's Island during the colonial era before reverting to its indigenous name in 1973. It is connected to the mainland via the Denton Bridge to the west and is characterized by alluvial soils and extensive mangrove swamps. Its strategic location made it a vital administrative and commercial hub throughout the colonial period. The island's physical size is constrained, leading to high urban density within the city limits. The surrounding maritime ecosystem is defined by tidal fluctuations, with mangroves providing essential coastal protection against storm surges. Despite significant urbanization, the nearby wetlands continue to support diverse populations of waterbirds and marine life.
