The Eden Project under construction in June 2000. The project has become a popular visitor attraction in Cornwall, England, UK. Inside the two biomes are plants that are collected from many diverse climates and environments. The project is located in a reclaimed china clay pit, located 2 km (1.2 mi) from the town of St Blazey and 5 km (3 mi) from the larger town of St Austell.[2]..The complex is dominated by two huge enclosures consisting of adjoining domes that house thousands of plant species,[3] and each enclosure emulates a natural biome. The biomes consist of hundreds of hexagonal and pentagonal, inflated, plastic cells supported by steel frames. The largest of the two biomes simulates a rainforest environment and the second, a Mediterranean environment. The attraction also has an outside botanical garden which is home to many plants and wildlife native to Cornwall and the UK in general it also has many plants that provide an important and interesting backstory, for example, those with a prehistoric heritage.
