There is something fascinating about the intricate work that goes into making a Lego structure. In this special event, Lego artist Warren Elsmore will bring London's most iconic landmarks to life using the world's most popular toy. Big Ben, O2, Olympic Stadium and St Paul's Cathedral are just some of the pieces to be displayed. But what's London without the routemaster bus, the black cab or a red telephone box? During his residency, Warren will also build a 2m tall scale model of the ArcelorMittal Orbit using 100,000 tiny bricks. Simply awesome. Please arrive on time as latecomers may not be admitted.
