Festival of Britain construction site on the corner of Waterloo Road and Tenison Way, Waterloo. A lorry delivers bags of Sowcem cement; on the bags the slogan 'Cheapest in the World, Ferrocrete'. Three workmen stand behind the lorry. On the site is a steam crane. To the left is the Shot Tower, the only original structure on the Festival of Britain site to remain; it was built for Thomas Maltby and Co Lead Works in 1826, and designed by David Riddal Roper. Hugh Casson, director of architecture for the Festival of Britain, described it as "an extraordinary device. It's a factory chimney, with a staircase inside it, and you take hot lead up to the top, and you drop it down, in drops, and the drops don't make tears as you'd expect, to get thicker as they go, they're absolutely perfect globes, and they're tiny, you see, as you know, I mean, they're absolutely wee, like the shot you get inside a cartridge". A radio beacon was constructed on the top for the Festival, but was demolished later. To the right, the tower encased in scaffolding formed part of the Health Pavilion. The Festival of Britain was a nationwide event that took place in the summer of 1951. Originally intended to mark the centenary of the Great Exhibition of 1851, it became a way to celebrate Britain and its achievements rather than including international themes. The construction of the Festival on its flagship South Bank site required the demolition of the industrial and residential buildings between Waterloo Bridge and County Hall. After the Festival, the South Bank site was cleared of all festival infrastructure except the Royal Festival Hall on the orders of Winston Churchill, who saw the Festival as a beacon for socialist ideas. This site was cleared and Hayward Gallery and a block of the Shell Centre, now known as The Whitehouse Apartments, was built here.
