James Turrell, Deer Shelter
http://www.ysp.co.uk/view.aspx?id=404

Turrell is an artist of international acclaim, renowned as a 'sculptor of light'. For over 40 years he has used light and space to create art installations which extend and enhance perception - from indoor pieces which baffle the senses, creating an illusion of infinite diffused light, to outdoor Skyspaces.

"James Turrell has created the Skyspace at YSP within the Park's 18th-century Grade II Listed building - the deer shelter. His work does not alter the shape of the landscape or disturb the tranquillity of the site, but creates a place of contemplation and revelation, harnessing the changing light of the Yorkshire sky. The Deer Shelter Skyspace consists of a large square chamber with an aperture cut into the roof. Through this aperture the visitor is offered a heightened vision of the sky, seemingly transformed into a trompe l'oeil painting."
