was described as "a tonic for the nation" by Herbert Morrison, the Labour Party government minister responsible for the event, the Festival of Britain aimed to demonstrate Britain’s recovery from World War II by showcasing the best in science, technology, arts and industrial design. It ran from May to September 1951, and by June the following year most of it had been dismantled, following the victory of Winston Churchill and the Conservative Party in the general election of 1951. The Royal Festival Hall is the only building from the Festival of Britain that survives. 1960s From 1962 to 1965, the Royal Festival Hall was extended towards the river and Waterloo station and refurbished. The London County Council (later, Greater London Council) decided in 1955 to build a second concert hall and an art gallery on the eastern part of the South Bank site previously occupied by a lead works and shot tower (and which had been earmarked as a site for the National Theatre). It was another 12 years before the Queen Elizabeth Hall and the linked Purcell Room opened to the public. Together, they were to be known as South Bank Concert Halls. In 1968, the Hayward opened, under direct management of the Arts Council. The new buildings had their main entrances at first floor level and were integrated into an extensive elevated concrete walkway system linked to the Royal Festival Hall and the Shell Centre. This vertical separation of pedestrian and vehicle traffic proved unpopular due to the difficulty pedestrians had in navigating through the complex, and the dark and under-used spaces at ground level below the walkways. 1980s Following abolition of the Greater London Council in 1986, the South Bank Board was formed to take over operational control of the concert halls. The following year, the South Bank Board took over the administrative running of the Hayward from the Arts Council. Collectively, the arts venues, along with Jubilee Gardens, became the South Bank Centre, responsible to Arts Council England as an independent arts institution (after transitional arrangements). 1990s The walkway on the east side of the RFH, running along Belvedere Road towards the Shell Centre was removed in 1999–2000, to restore ground level circulation. The Waterloo Site (the late 1960s buildings) has been the subject of various plans for modification or reconstruction, in particular a scheme developed by Richard Rogers in the mid-1990s which would have involved
