Portishead (Port Code:GBPHD) has a long history as a fishing port. As a Royal Manor it expanded rapidly during the early 19th century around the docks, with supporting transport infrastructure. A power station and chemical works were added in the 20th century, but the dock and industrial facilities have since closed and been redeveloped into a marina and residential areas.
The Dock subsequently played its part in World War II for incoming supplies from various parts of the world. It played an especial role in the Normandy landings on D-Day and onwards, when large numbers of vessels loaded with munitions and supplies set off down the Bristol Channel for France.
In June 2000 work started on the construction of a new lock barrel at the entrance to Portishead Dock, which would enable sailing craft of all sizes to gain access to the new marina. For the first time ever the huge stone built lock was emptied completely of water so that workmen could commence work. The new marina was opened on time in May 2001. The former dock is now one of the best equipped marinas in the South West. It is owned by Quay Marinas.
