Eden Project

The Eden Project near St Austell in Cornwall, southwest England, is one of the world's most extraordinary visitor attractions: a series of giant interlocking geodesic biome domes built into a former kaolinite (china clay) pit, 60 metres deep and 500 metres wide, which was exhausted of clay and entirely derelict when the project was conceived in the late 1990s. The project opened in 2001 and the pit, once a symbol of industrial extraction, was transformed into a living landscape demonstrating the interdependence of plants and people. The Rainforest Biome is the largest indoor rainforest in the world: a 55-metre-high dome maintaining a tropical climate year-round, housing over 1,000 plant species from rainforests of West Africa, Malaysia, Amazonia, and Oceania. Orchids, rubber trees, cocoa, banana, coffee, and towering canopy trees create a genuinely immersive tropical environment even in the depths of a Cornish winter; a mist system and waterfall maintain humidity throughout. The Mediterranean Biome, smaller but equally impressive, recreates the landscapes of the Mediterranean, southern California, South Africa's fynbos, and the Canary Islands, with olive groves, citrus, and colourful seasonal plantings. The outdoor gardens, terraced into the pit walls, grow produce, wildflowers, and sculptural installations that change through the seasons. A zip wire runs across the pit at 45 metres, offering a dramatic aerial view of the domes. The Eden Sessions, a series of open-air concerts held in the pit during summer, feature major artists against the domes as backdrop. A full visit covering both biomes, outdoor gardens, and food takes four to six hours.
