This is part of the reinforced concrete section from Ronan Point, a high rise residential building in London. Rapid construction was the principal aim in the design of the 23-storey building, built for Newham Council in 1966-1968. Unfortunately, the design did not take into account all of the likely events. On 16th May, 1968, a gas explosion in one of the flats caused part of the building to collapse, killing five people and injuring seventeen.
