When you think about rainforests, you might think of somewhere with a tropical climate — somewhere like the Amazon or the Congo. But in fact, a very large rainforest can be found in a country famous for its dreary weather: the UK. The Eden Project, an attraction in southwest England, calls itself the world's largest indoor rainforest. Sometimes referred to as the "Eighth Wonder of the World," the Eden Project was created in 2001 from an old clay pit. It's famous for its two enormous biomes, which are designed to look and feel like rainforests and tropical regions from all over the world.

The Rainforest Biome is about 16,000 square meters in size, and is full of plants found in tropical climates, like sugarcane, pineapples and bananas. There are rare and unusual plants too, like the titan arum — a flower famous for its terrible smell that only blooms around once a year. The Mediterranean Biome is a little smaller at 6,540 square meters, but has plants from the Mediterranean and regions with similar climates, such as California, South Africa and Australia. The Eden Project is not just a place for people to look at plants, though — there is an environmental message behind the attraction, and it aims to teach visitors about the importance of looking after the environment. As well as activities and workshops that teach visitors about the importance of living sustainably, the Eden Project even offers courses for a university degree! And there's plenty of other things to see and do, too. Throughout both biomes, visitors can find art and installations which focus on important topics like climate change. And every year, the Eden Project hosts the Eden Sessions, a series of outdoor music concerts. Famous artists such as Amy Winehouse, Elton John and Oasis have performed at the Eden Sessions in the past.
