The Eden project, close to Mevagissey, is proof that not all millenium projects in England were as doomed as the Dome. This project would seem to have been an overwhelming success.

Put very briefly two huge domes were erected on what had previously been a china clay works and an imense work combining education and plants was started. However if you have even the slightest interest, you should go immediately to the website which gives some idea of the imagination, creativity and scope of the project.
