The Eden Project is celebrating its 25th anniversary on 17 March.

It's one of the largest indoor rainforests in the world.

The tourist attraction is in Cornwall on the south coast of England and has two massive domes called biomes, each filled with thousands of plants.

Peter Jones is one of the people in charge of looking after all of those plants, he says they like to show visitors "how things might look if you were to visit them for real".

Of course, the site didn't always look the way it does now, for 160 years it was a clay pit with no soil in sight.

It was then transformed into one of the country's most famous tourist attractions, which first opened its doors in March 2001.

Since then 25 million people have visited, including around 750,000 children on school trips.

Clouds can form at the top of the largest dome

  • 55 - The height of the largest dome in metres - that's taller than 11 double-decker buses on top of each other. It's so high that clouds can even form at the top.

  • 5 - The distance they had to drill down in kilometres so that they could use geothermal energy.

  • 4 - The area the indoor forest covers in acres - that's the size of almost three football pitches.

  • 60 - The average speed in miles per hour of the zip wire that visitors get to use - if they are brave enough. It's thought to be the fastest in England.
