The Temperate House at Kew Gardens is the world's largest surviving Victorian glass structure. It is seen here from Kew's Treetop Walkway which is 200 metres long and 18 metres above the ground. It also provides a novel view of the tree canopy. Work on building the Temperate House began in 1860. The octagons at either end were completed in 1861, the centre section in 1862 and foundations for the wings were part laid when work ceased in 1863. The Treasury had stopped the work because of the escalating cost and work did not resume until August 1895. It was finally completed in 1898.
