Spinnaker Tower is a 560 foot (170 metres) high viewing tower, constructed as part of the redevelopment of Portsmouth Dockyard. It opened in 2005 and is included within a waterside retail and restaurant complex, Gunwharf Quays. Modelled on a billowing sail, the Spinnaker Tower has changed Portsmouth's skyline and is visible for miles. It offers 360-degree views from the high viewing platforms across Portsmouth Harbour and the surrounding sea and landscapes, apparently to a distance exceeding 20 miles. You can also take tea in a high-level cafe, get married there, or abseil down the tower.
The attraction is managed under contract to Portsmouth City Council.
