Spinnaker Tower

The Emirates Spinnaker Tower is a 170-metre landmark observation tower in Portsmouth, England. It is the centrepiece of the redevelopment of Portsmouth Harbour, which was supported by a National Lottery grant. Its shape was chosen by Portsmouth residents from a selection. The tower, designed by local firm HGP Architects and engineering consultants Scott Wilson and built by Mowlem, reflects Portsmouth's maritime history through its being modelled and named after a spinnaker, a type of sail that balloons outward. The tower was opened on 18 October 2005.

The tower is owned by Portsmouth City Council, but operationally it is managed by Continuum Leading Attractions, a cultural attractions group based in York. Continuum also runs five other visitor attractions across the country. Following a commercial sponsorship deal with Dubai-based Emirates airline, the tower was renamed in July 2015.
