I visited the Project in mid October in pouring rain; not a problem in the two indoor greenhouses but a considerable one outside, bearing in mind that this part covers by far the largest area, especially if you are hoping to take photographs. In addition, although the growing season in Cornwall goes on longer than in Yorkshire, some of the planted areas were past their best.A few facts …….
- the exhausted china clay pit in which the Project is built covers an area the equivalent
of 35 football pitches
- 83,000 tonnes of soil was made from recycled waste to provide the growing medium
- the Tower of London would fit inside the Rainforest Biome
- the rainforest biome is officially the biggest lean-to greenhouse in the world
- the idea for the bubble-like structures came to the architect while he was doing the
washing up
- the steel frame of the biomes consists of two layers, mainly in the form of hexagons
- there are three layers of the transparent covering material which has a twenty-five
year guaranteed lifespan
- the biomes are so lightweight for their size, that in high winds they are more likely to
blow away than blow down; however, they are firmly held down with ground anchors!
Travelling to the Project is along purpose made roads to a series of car parks; each named after a fruit; I parked in ‘Lime’. You need to remember which one you are leaving car in, as it would take some finding if you forget! Parking is free and a bus takes visitors to the Visitor Centre through which you pass to pay and enter the site. Once through you can either walk down the zigzag path or if you find this a daunting, take the land train. There is also a lift not too far away.
On entering, you will receive A Guide. Try to take a few minutes to read it before you set off to get some idea of the site layout and some of the information. Reading it afterwards only makes you realise how much you have missed or ignored! If you can, visit the website, www.edenproject.com which gives lots of information to help plan your visit.
There are four main areas ……
- the Outdoor biome
- the Rainforest biome
- the Mediterranean biome
- the Core
The Outdoor Biome doesn’t need a roof because it is our own climate, i.e. that found between the Mediterranean and the Arctic. It covers 30 of the 35 football pitches (about 85% of the whole site). It is built into the base and around the steep slopes of the pit and is accessed through the Visitor Centre and down a zigzag path between banks of ferns and horsetails, some of the earliest plants to grow on the planet. At the bottom is an area in which familiar vegetables and flowers are growing just like they do at home or at the allotment - only to an impressive standard! Other paths then wind up and down the slopes through a series of other gardens featuring crops and other plants from various parts of the world. The poor weather on the day precluded a more in depth look, which leaves me with an incentive to make a future visit! Also in the bottom part of the site is the amphitheatre which provides a venue in the summer for live music concerts and in winter an ice skating rink.
Access to the indoor biomes is via The Link, literally a building linking the two biomes and housing a range of facilities, including toilets, information, cafes, restaurant, etc. There is even a small cloakroom (unattended).
The Rainforest Biome is the larger of the two ‘greenhouses’ with a daytime temperature from 18 to 35 degrees C and a humidity level of 60% (rising to 90% at night). There is a cool room for any visitor who finds the heat too much. The path winds through various tropical zones up into the top of the back wall, often between massive jungle plants from tropical islands, Malaysia, West Africa and tropical South America. Rubber, bananas, bamboo, sugar cane, coffee, pineapples, cocoa, spices, etc. all come from plants growing in this climate. Many of the plants grow at a phenomenal rate in these conditions and have to be pruned regularly. This job is carried out using cherry pickers and abseilers.
The Mediterranean Biome is far more open than the tropical one and the temperature is a comfortable 25 degrees C maximum. Although smaller than the rainforest biome, it is still enormous. Areas of the world covered, in addition to the Mediterranean basin itself, include South Africa and California. Plants from these parts of the world often have to cope with drought and poor thin soils. However, irrigation, fertilisers, etc. make this climatic zone a rich environment for vegetable, wine, fruit and flower production. There are citrus fruit, grape vines, olive trees and peppers, together with a wide range of flowers grown for the florist trade.
The Core is the newest part of the Project, opened in 2006, as the education centre. Architecturally, it is as spectacular as the domes if you take the time to look at it and to read up on its design, with its roof spirals which take its inspiration from plant forms such as pinecones, pineapples and sunflowers. The centre has two exhibition areas. The ground floor concentrates on environmental issues such as conservation, food production, climate change, renewable energy, etc., while the upper floor provides for schools programmes, more exhibitions, workshops, etc. In the middle of the building is a 70-tonne sculpture ‘Seed’; made from Cornish granite; it is the largest sculpture from a single piece of rock since Egyptian times and is twice the weight of any of the stones at Stonehenge. The spiral concept also carries on through this very impressive work of art.
Back up to the top at the Visitor Centre, there is the expected plant sale area and gift shop that has an extensive and excellent range of products on offer.
The £14 entrance fee (£10 for seniors, £5 for children 5 yrs and over, £35 for a family of five) is not cheap but is good value for money.
I make no apology if all this sounds like a free advertisement for the Project. It is a fascinating place, even if you are not into gardening; to an enthusiast like me it is doubly so and I would recommend it to anyone visiting the area.
