James Turrell (born May 6, 1943) is an American artist primarily concerned with Light and Space. Turrell was a MacArthur Fellow in 1984. Turrell is best known for his work in progress, Roden Crater, a natural cinder cone crater located outside Flagstaff, Arizona that he is turning into a massive naked-eye observatory.
Access to Roden Crater is limited to friends, though devoted fans can gain access by completing the "Turrell Tour", which involves seeing a Turrell in 23 countries worldwide. During May 2015, Roden Crater was open to a select group of 80 people, as part of a fund raiser, by allowing visits of 20 people per day during the course of four days, at a cost of $6,500 per person. As Roden Crater has been long shrouded in secrecy, fans have attempted to sneak in without the artist's permission. Some have succeeded.
In the 1970s, Turrell began his series of "skyspaces" enclosed spaces open to the sky through an aperture in the roof. A Skyspace is an enclosed room large enough for roughly 15 people. Inside, the viewers sit on benches along the edge to view the sky through an opening in the roof.
