Celestial Vault (Hemels Gewelf)
Celestial Vault is a monumental earthwork by artist James Turrell, located in the Kijkduin dunes. Created in 1996 and restored in 2008, it's Turrell's only outdoor artwork in the Netherlands. The elliptical bowl, 40 meters wide and 5 meters high, features slanted stone benches in the center. Lying down and looking up, the sky appears as a curved dome - a unique meditative experience.
