Inspired by the greenhouses of its horticulturist creator, for 10 points, identify this Hyde Park structure built by Joseph Paxson to house London's Great Exhibition of the Industry of All Nations of 1851, so named for its iron-and-glass construction.
In its later years, this structure housed the television studio of John Logie Baird, and a training station for the Royal Navy.  An early plan for this structure, featuring brick construction and a notable dome, was drawn up by Isambard Brunel, who engineered the two water towers associated with the final design. Moved to Sydenham Hill shortly after construction, it burned down there in 1936.   Before being moved, its center transept included the world's largest organ, while early flush toilets, a massive series of fountains, and thousands of exhibits were all found within its walls.  Inspired by the greenhouses of its horticulturist creator, for 10 points, identify this Hyde Park structure built by Joseph Paxson to house London's Great Exhibition of the Industry of All Nations of 1851, so named for its iron-and-glass construction.
