This virtual tour shows three of the City of London's landmark buildings - the Lloyds Building, 30 St Mary Axe (The Gherkin) and St Helen's. The latter was previously known as the Aviva Tower and was the first building in the City of London to be taller than St Paul's Cathedral. It is now named after the historic city church, St Helen's, which is on Bishopsgate nearby. Please click the thumbnail panorama below to view the full-size virtual tour.
