Canary Wharf in London’s Docklands is a world-class symbol of successful urban regeneration. Where 30 years ago there was a wasteland of derelict wharves, today gleaming glass and steel offices tower on the city’s eastern skyline.

With 35 buildings packed onto 97 acres by the Thames, it is a bustling financial centre second in the UK only to the City, a few miles to its west. Among its tenants are some of the world's biggest banks, including Barclays, Citigroup and HSBC.
