The Maritime Quarter, or Swansea Marina, is a residential area of Swansea, Wales, UK located immediately south of the city centre shopping core. It falls within Swansea's Castle ward. The area is bounded by Brynmill to the west, Swansea Bay to the South, the River Tawe to the east and the A4067 to the north.
The area comprises a mixture of housing ranging from 1980s low-rise apartment blocks around the old South Dock to town houses arranged in quadrangles in the south eastern part of the area, which were built in the 2000s (decade). The Marina, is unusual in that planning approval was given on condition that a significant proportion of the development be sold to Housing Associations for social housing. The tallest building in Wales, the Meridian Quay Tower is located in the area.
Formerly the South Dock, during the 1980s it underwent significant brownfield re-development in the early 1980s with the building of many low rise apartment blocks in the area around the South Dock. On the site of the Sainsbury's superstore, once stood the Weaver building. Built in 1897 by the French architect François Hennebique It was used for corn storage and it was the first steel reinforced concrete building built in Europe.
Originally the city council decided to fill in the South Dock. This was done by a developer whose brother was a councillor at the local council. Later on, the same company was paid to dig out the South Dock again to create the marina. The developer is now imprisoned in Swansea Prison.
