The Crystal Palace was a cast iron and glass exhibition hall constructed in London for the Great Exhibition of 1851.  With an interior space of 92,000 square metres and a height of 33m (large enough to accomodate full-sized living elm trees) it was a spectacular building.

It was first erected in Hyde Park, then reassembled after the Exhibition in south London.  It was destroyed by fire in 1936.
