Spiraling 288 meters (941 feet) upward from its base, the Pinnacle tower will form the apex of an emerging cluster of tall buildings in the centre of London’s financial district. Designed to make substantial contribution to the public realm, the project involves reopening a ground-level pedestrian passageway closed to pedestrians by a previous building on the site since the 1980s and linking a number of important public spaces along Bishopsgate and St. Mary Axe.
