What is it? Modelled on a sail to reflect the city’s seafaring history, this landmark observation tower is two and a half times the size of Nelson’s Column in Trafalgar Square – making it the tallest climbable structure outside the UK capital. Originally called the Portsmouth Millennium Tower, it’s hard to believe it’s coming up to its second decade: from the stomach-turning external glass lift to the panoramic decks, it still feels super state-of-the-art.
Why go? For the Sunset Sundays session, when you can watch nature’s very own light and colour show from 100 metres above sea level, accompanied by live music on the three viewing decks and a sky-high pop-up bar. Grab an Isle of Wight Gin and tonic and drink in the killer views of the Solent and the South Coast.
