Eden Project

Cornwall, England, United Kingdom

---

The Eden Project is a world-renowned educational charity and visitor attraction in Cornwall, England, built in a reclaimed 200-foot-deep clay pit about 3 miles northeast of St Austell and opened to the public in 2001. Often called the “Eighth Wonder of the World,” it features two massive, futuristic geodesic biomes—transparent hexagonal domes made of steel and plastic panels—that house the world’s largest indoor rainforest (maintained at 18–35°C with thousands of tropical plants like bananas and rafflesia) and a warm-temperate Mediterranean biome filled with olive trees, citrus groves, and colorful flowers. Beyond the biomes, visitors explore extensive outdoor gardens showcasing useful plants (food crops, medicines), wild Cornish flora, and interactive art, plus adventure activities like England’s longest zip wire, a giant gravity swing, and Nature’s Playground for children. As both a global garden and a social enterprise, the Eden Project’s mission is to inspire people to care for the planet by teaching about biodiversity, sustainability, and the vital role plants play in our lives, while also hosting concerts, seasonal events, and family workshops that have drawn over 19 million visitors and generated nearly £2 billion for the local Cornish economy since opening.
