Panoramic view of the geodesic dome structures of the Eden Project, a large-scale environmental complex near St Austell, Cornwall, England. The project was conceived by Tim Smit and is made out of hundreds of hexagons (transparent biomes made of ETFE cushions) that interconnect the whole construction together. The project took 2½ years to construct and opened to the public in March 2001.Photo credit: Jürgen Matern
