The Eden Project (Cornish: Edenva) is a visitor attraction in Cornwall, England. 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.

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.

Since 2002, the Project has hosted a series of musical performances, called the Eden Sessions, usually held during the summer.
