The Eden Project is a sixty metre deep, fifteen hectare (34 acre) china clay pit overlooking St Austell Bay in Cornwall, houseing two plant conservatories, with external grounds of 12 hectares. One of the conservatories is over 50 metres, taller then Nelson's Column. The other conservatory creates a Warm Temperate climate and house plants from many regions such as South Africa, South Western USA and the Mediterranean. With trees, vines and hundreds of colourful flowers. At the entrance to the pit, is the visitors centre, and on site are restaurants and shops celebrating the many varied foods and plants from around the world. Croft Farm is just two miles from the famous Eden Project, a magnificent living theatre of plants from around the world, designed to inspire and inform visitors and to provide an international forum for environmental research and debate. The plants range from giant mahogany trees to tiny orchids. They are housed under two giant conservatories called biomes, which are self-supporting structures of hexagons, the largest of which is 45 metres high and big enough to house the Tower of London! As well as the Biomes you can visit the lake and enjoy the attractions from live music and performance art to horticulture, cookery and painting events. The centre is open throughout the year.
