Philip Johnson’s Glass House, in New Canaan, Connecticut—which opens for the season today, May 1—is offering self-guided tours ($75) for the first time.

Visitors, annotated map in hand, can take their time exploring the legendary all-glass, one-room landmark, as well as the other Johnson-designed structures (including painting and sculpture galleries, the Pond Pavilion, and the Lincoln Kirstein Tower) on the 49-acre grounds. Guides will also be on site to answer any questions. Note that self-guided tours are only offered on select dates (one Thursday and one Saturday per month), and guided tours are still available.

Another Glass House milestone that’s launching this season: the new Fujiko Nakaya: Veil exhibit, the first-ever site-specific project to engage the house itself. The Japanese artist known for his fog sculptures will wrap the property in a dense mist, created by fresh water pumped at high pressure through 600 nozzles. Once an hour, the house will be completely enveloped and disappear from sight; those on the inside will lose that sense of being outdoors for which the Glass House is known.
