The complex is dominated by two huge enclosures consisting of adjoining domes that house thousands of plant species,and each enclosure emulates a natural biome. The domes consist of hundreds of hexagonal and pentagonal, inflated, plastic cells supported by steel frames. The first dome emulates a tropical environment, and the second a Mediterranean environment.
The Eden Project is a visitor attraction in Cornwall in the United Kingdom. Inside the artificial biomes are plants that are collected from all around the world. The project is located in a reclaimed Kaolinite pit, located 1.25 mi (2 kilometres) from the town of St Blazey and 5 kilometres (3 mi) from the larger town of St Austell, Cornwall.
