Spinnaker Tower
The focal point of the lively Gunwharf Quays development of shops and bars, the Spinnaker Tower is a striking addition to Portsmouth's skyline. The slender structure evokes a mast with a billowing sail, and rises to a height of 558 feet. An elevator whisks you to three viewing platforms 330 feet high for thrilling all-around views of the harbor and up to 23 miles beyond. There's a café on one of the viewing platforms (admission with prebooked High Tea only) and a bar on another (admission with £10 prebooking redeemable against the cost of drinks).
