Which building hosted the Great Exhibition during Victoria's reign?

The Crystal Palace hosted the Great Exhibition during Queen Victoria’s reign.

The Great Exhibition of the Works of Industry of All Nations opened in Hyde Park, London, on 1 May 1851. Joseph Paxton designed its vast temporary building, which used an iron frame and enormous quantities of glass; its dazzling appearance quickly earned it the name Crystal Palace.

Prince Albert played a leading role in organising the exhibition, which displayed machinery, manufactured goods, raw materials, and artworks from Britain and many other countries. Queen Victoria officially opened the event, and more than six million visits were recorded before it closed on 15 October 1851.

The building was dismantled after the exhibition and re-erected at Sydenham in south London in 1852. It later became a major cultural and entertainment venue, but the original Great Exhibition itself took place in Hyde Park. Royal Albert Hall was built later and did not host the 1851 event.
