Crystal Palace Looking To Rebuild?:

"Architect Ray Hall dreams of rebuilding the long-lost wonder, and now claims the battle is half won. An undisclosed private donor has promised half of the £60 million required to resurrect the iconic greenhouse."

The Crystal Palace was built for The Great Exhibition of 1851, as celebration of the glories of the British Empire. Not much is left of the building which moved from Hyde Park to Sydenham Hill in 1854, which burned down in the 1936, but you can go visit the foundations. Nothing in the article about where the new palace would go (on top of the old foundations?), but it is said that the structure will only be a quarter of the size of the original, and use a hi-tech glass which will generate enough electricity for 10,000 houses. The tech component is in keeping with the original, which was a extremely innovative structure for it's time, and paved the way for the steel frame architecture of 20th century skyscrapers.
