A WORK of art said to be of national significance was unveiled at the Yorkshire Sculpture Park.
The Skyspace is an £800,000 gift from the National Art Collections Fund.
Sculptor James Turrell created a light-drenched space in a listed building which was originally a shelter for deer.
The work involved excavating 2,000 tons of rock and soil, then putting 370 tons of concrete and steel back in to create a part-buried chamber.
The result is a part-buried chamber, 29ft square and 24ft high.
