James Turrell’s “skyspace” Light Reign is the only thing that’s really on always-and-forever display at the Henry. It’s an outdoor room that lives like a barnacle on the side of the museum, with an opening in the ceiling so that you can sit and watch the sky go by. The experience is mind bogglingly more fascinating than you’d think, which is why Turrell has “skyspaces” all over the world. The Henry’s is furniturey, ringed with wooden bench seating. $10 suggested.
Artful Reproductions: The permanent collection is full of treasures to be discovered for a first time or rediscovered anew. The wall of diminutive snuffboxes—each one delicately painted with a scene that draws you into its tiny alternate reality—is in itself enough to warrant multiple visits. $7 suggested.
