In March this year, the largest botanical gardens of their kind in the world were opened. The Eden Project in Cornwall, south-west ­England, provides a habitat for trees and plants from three different climatic zones. Largely ­financed by the European Union and the British Millennium Fund, the gardens, with their huge greenhouses, are proving a great magnet for the public. During the construction period alone, the site drew some 500,000 ­visitors, and in the first two months after the gardens were opened, 400,000 people came to see the botanical and architectural ­attractions.
