Top things to do in London, England
"The ferns, fig trees and purple African lilies that clamber up the final three storeys of the 'Walkie Talkie' skyscraper are mere wallflowers at this 155m-high rooftop garden – it's the rather extraordinary 360-degree views of London (the best in the City) that make this vast, airport-terminal-like space so popular (advance booking recommended). Located on the 35th floor of 20 Fenchurch St, the Sky Garden has front-row seats for the Shard and vistas that gallop for miles east and west."
