Spinnaker Tower Portsmouth: What to See and Know

Spinnaker Tower Portsmouth is a 170-metre (560-foot) landmark observation tower in Portsmouth, England. Opened in 2005, it is the centrepiece of the redevelopment of Portsmouth Harbour and was built as a signature project to revitalise the waterfront for the new millennium.

The tower is distinctive not only for its height, but also for how its design became part of Portsmouth’s public story. Its redevelopment was supported by a National Lottery grant, connecting the structure to a wider transformation of the harbour area.

What is Spinnaker Tower Portsmouth?

Spinnaker Tower is Portsmouth’s 170-metre observation tower and a landmark of the harbour waterfront. Its three viewing platforms sit one above another at heights of 100 metres, 105 metres and 110 metres, giving the tower a clearly layered visitor experience.

The tower was opened in 2005 as the centrepiece of Portsmouth Harbour’s redevelopment. That redevelopment received support from a National Lottery grant, while the tower itself was presented as a signature project intended to revitalise the waterfront as part of the new millennium.

Why does Portsmouth’s tower have a sail-shaped design?

Spinnaker Tower takes its name from a spinnaker, a type of sail that balloons outwards. The name reflects the tower’s distinctive sail-inspired form and its setting beside Portsmouth Harbour.

The shape was not simply presented as an unselected design. In a 1998 public poll, Portsmouth residents chose the tower’s design from three options. They selected it over the alternatives known as The Globe and The Triple, making the tower’s form a decision shared publicly by the city’s residents.

What can you see and do inside Spinnaker Tower?

Spinnaker Tower has three viewing platforms, including the Sky Deck at 100 metres. The viewing levels are arranged at 100 metres, 105 metres and 110 metres, with each contributing to the tower’s changing experience at height.
