'Light is a powerful substance. We have a primal connection to it.' Internationally acclaimed Californian artist James Turrell uses light and space as a medium to challenge perception and explore "'mankind's place in the universe". Inspired by astronomy, physics, architecture and theology, the 72 year old artist has had over 160 solo exhibitions worldwide and is said to be one of the most influential artists of the past fifty years.

Light installations throughout the grounds include St Elmo's Breath, housed in an 18^th century water tower and Seldom Seen Skyscape 2004 inside a wooden viewing chamber surrounded by trees. This exhibition has been 15 years in the making and definitely sounds well worth the wait.
