Huge cardboard tower toppled in the City of London

Crowds cheered as a huge 20m-high cardboard structure dubbed The People's Tower was brought crashing to the ground on Sunday 21 July.

Over 1,000 boxes were used to create the tower, designed by artist Olivier GrossetĂȘte and inspired by the Guildhall building in the City of London -- London's traditional financial district.

Box-building workshops took place during the week, with the tower constructed on Saturday 20 July.

The People's Tower was part of the Fantastic Feats festival, the theme of which is "the building of London".
