Kew Gardens, a World Heritage Site, houses the largest botanical and mycological collections in the world. Established in the early 18th century, the site evolved from royal residences and private estates. In 1840 it became a national botanic garden. The gardens and pleasure grounds were enlarged and a number of significant buildings constructed, including Decimus Burton's and Richard Turner's wrought iron and glass Palm House, and the Temperate House, which is the largest surviving Victorian glasshouse. These are two of four Grade I listed buildings located at Kew.
