A UNESCO World Heritage Site, these extensive, historic and beautiful gardens feature elements illustrating significant periods of garden and landscape art from the 18th to the 20th centuries, as well as a plant collection second to none in the world. Since their creation as a royal estate in 1759,
Kew Gardens (as they are commonly known) have made a significant and uninterrupted contribution to the study of plant diversity and economic botany. The gardens cover 120 hectares (300 acres) and are over 1.5 km long. They contain several major glasshouse complexes, not least the famous Palm House opened in 1848, together with a museum and several follies.
