The Spinnaker Tower is a 170-metre (560 ft) landmark observation tower in Portsmouth, England. It is the centrepiece of the redevelopment of Portsmouth Harbour, which was supported by a National Lottery grant. The tower's design was chosen by Portsmouth residents from a selection of three different designs in a 1998 public poll.[5] It has three viewing platforms one on top of the other at heights of 100 m, 105 m and 110 m.
The tower was designed by local firm HGP Architects and engineering consultants Scott Wilson and built by Mowlem with steelwork by Butterley Engineering.[6] The Spinnaker Tower reflects Portsmouth's maritime history through its design and is named after a spinnaker, a type of sail that balloons outward.[7] The tower was opened on 18 October 2005.
The tower is owned by Portsmouth City Council and is operationally managed by Continuum Leading Attractions, a cultural attractions group based in York. Continuum also runs five other visitor attractions across the country.
The Spinnaker Tower was repainted and rebranded as the "Emirates Spinnaker Tower" from July 2015 following a five-year commercial sponsorship deal with Dubai-based Emirates airline. The Emirates sponsorship deal expired in 2020 and the tower reverted to its original all-white paint scheme and name in April 2021. On 5 May 2023, it was announced that Macmillan Cancer Support would become the tower's new sponsor beginning in June.
