At 800 feet, this 2013 addition to the London skyline currently offers the highest vantage point in Western Europe. Designed by the noted architect Renzo Piano, it has attracted both admiration and disdain. While the building itself is generally highly regarded, many felt it would have been better sited in Canary Wharf (or perhaps Dubai), as it spoils views of St. Paul's Cathedral from traditional vantage points such as Hampstead's Parliament Hill. No matter how you feel about the building, there's no denying that it offers a spectacular 360-degree view over London (extending 40 miles on a clear day) from viewing platforms on floors 68, 69, and 72—almost twice as high as any other viewpoint in the city. Digital telescopes provide information about 200 points of interest. There's a weather guarantee that lets you return on a more clement day if visibility is seriously impeded, and various themed events like wine tastings or silent discos are offered at an extra charge. If you find the price as eye-wateringly high as the viewing platforms, there's a less dramatic but still very impressive (and free) view from the lobby of the Shangri-La hotel on the 35th floor, or, in the evenings, the hotel's chic Gong bar on the 52nd floor (over-18s only).
