A skyspace is an architectural design in which a room, which is painted in a neutral color has a large hole in its ceiling which opens directly to the sky. The room, whose perimeter has benches, allows observers to look at the sky in such a way as though it were framed. LED lights which surround the hole can change colors to affect the viewer's perception of the sky.
The design is the work of American artist James Turrell. As of 2013 over 82 skypaces have been installed worldwide. This is the one in the Yorkshire Sculpture Park, Wakefield.
The sign at the entrance said there may be queues for this exhibit! Had the place to myself and had great fun working different angles.
