Jake and Dino Chapman's 'The Good, The Bad and The Ugly' rusty dinosaurs have been outside the Gherkin for a year but now they have left, allegedly for Hampstead Heath, where I think they will be happier. I know I will be as they weren't my favourite pieces. I did love the Gorilla holding a fish the plaza had in 2012 and I'm eager to see this year's Sculpture in the City art works. But while I won't miss the dinosaurs, I will miss Robert Indiana's 'One Through Zero' which was outside The Willis Building. Here's a picture of 456 if you missed them - and one of the gorilla too - you'll have to go to Hampstead to see the dinosaurs!
