Sky Garden

Top choice viewpoint in The City

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.

Dubbed the 'Walkie Talkie' by unimpressed Londoners, this bulging skyscraper didn't get off to a good start when it opened in 2014, as its highly reflective windows melted the bodywork of several cars parked below. Its overbearing design also earned it the Carbuncle Cup for the worst new building in the UK in 2015.

The complex includes a restaurant, a brasserie and three bars. If tickets have sold out, reserve a table at the cafe-bar Sky Pod to still gain access to the garden – though you may need to buy a drink.
