Canary Wharf, the home of London’s financial district, is the undisputed stomping ground of men in suits, spotted most days striding between office and power lunch, talking loudly on their phones. But plug your ears and look upwards – far more interesting than their overheard conversations is the array of seriously impressive, thoroughly modern architecture that houses these besuited businessmen. Towering skyscrapers give this corner of London a modern makeover and should be a must-see for any architecture buff.
