Perfectly located near London Bridge on the south bank of The Thames, Renzo Piano's Shard gives the best view of one of the world's most iconic cities (and all her icons), making them feel at once close to you, and close to each other. On one side of the deck you can look west and see The London Eye, Westminster Abbey, and Big Ben.
Then walk around a little further and St Paul's Cathedral is just there, sitting proud, opposite The Tate Modern.
Further along you can almost reach out and grab The Walkie Talkie and The Gherkin and look down to see The Tower of London and the Tower Bridge. The towers of Canary Wharf are further to the east.
Even for those who aren't fans of The Shard, it is pretty much now the only place in London where you can't see the damn thing.
