A London Underground sign is positioned beneath the tall architecture of The Shard at London Bridge. Looking upwards to the point of the Shard's pinnacle, we see the roof of an entrance to the Underground station a few metres from the London Bridge mainline station, a transport hub and gateway to the City of London and Southwark on the Southbank. Standing 306 metres (1,004 ft) high, the Shard by Italian architect Renzo Piano is currently the tallest building in the European Union. It dominates this borough of Southwark in south London.
