the main exhibition hall at the Great Exhibition of London, held in 1851 in Hyde Park. The Crystal Palace was designed by the engineer J. Paxton, who made use of his experience in designing greenhouses.
The Crystal Palace introduced into practice the principle of using a metal (iron) frame consisting of identical structural units holding glass panes. Its design had an important effect on the development of the more progressive tendencies in architecture and construction engineering in the 19th and early 20th centuries. In 1854 the Crystal Palace was moved to Sydenham, and in 1936 it was destroyed by fire.
