The Sustainability Centre is situated in heart of the South Downs and now occupies the land that was once HMS Mercury.
The centre aims to educate, enable and inspire people from all walks of life to make positive changes to the way they live and work.
The Centre is spread across 55 acres of woodland and natural chalk downland and is owned by a charity, the Earthworks Trust, which was established in 1995.
