In the early 1990s Andy Goldsworthy was invited to propose a project for Cumbria, a region of outstanding natural beauty in Northern England where the landscape has been molded for centuries by agriculture and in particular by sheep-farming. His response was to repair or rebuild a swathe of Cumbrian sheepfolds, stone enclosures used for gathering, sheltering and washing sheep, reconstructing them to incorporate or contain artworks with the intention that, wherever possible, the folds would still be accessible to sheep. Among the sculptures are slate works and balanced stones embedded in walls and a series of sixteen holding folds along a drove road, each containing a massive glacial boulder rolled down from the nearby hillside. Work began in January 1996, and, despite a hiatus in 2001 when the devastating outbreak of foot-and-mouth disease effectively closed off the land, by 2006 more than forty structures had been completed. It is this extraordinary project that forms the core of Enclosure.
