Brighton Marina is an artificial marina situated in Brighton, England. It features a working harbour and residential housing alongside a variety of leisure, retail and commercial activities. The construction of the marina itself took place between 1971 and 1979, although developments within it have continued ever since. The marina covers an area of approximately 127 acres (0.51 km2).
The Brighton Marina Act 1968 provided the legal basis for the construction of the marina. Brighton Corporation purchased the foreshore at the Black Rock site from the Crown Estate Commissioners for £50,000 on 1 March 1972. On the same day the land was leased to the Brighton Marina Company for a period of 125 years. The architect of the original plan was David Hodges of the Louis de Soissons Partnership. Construction of the marina commenced in 1971 and was opened for use in 1978. The marina was officially opened by Queen Elizabeth II on 31 May 1979. The original funders were the National Westminster Bank, the Electricity Supply Pension Fund and the Royal Insurance.
