You know it’s almost summer when the Metropolitan Museum of Art opens up its fabulous Roof Garden once again, complete with amazing Central Park views, snack and cocktail bar (the Met Roof Garden New York is always an excellent spot for a date, or to bring out-of-town visitors), sunshine and breezes, and, of course, the Met’s annual rooftop art installation. In summers past the Met Roof Garden has been the stage for some first-rate (and fun!) works by such renowned contemporary artists as Roxy Paine, Jeff Koons, Andy Goldsworthy, Sol LeWitt, Frank Stella, and Doug and Mike Starn, aka the Starn Twins, whose ever-changing piece “Big Bambu” utterly transformed the space last year.

This year the Metropolitan Museum of Art Roof Garden’s coveted commission went out to Argentine artist Tomás Saraceno, and he responded with a real dazzler, a brand new, perspective-skewing installation, Cloud City. Soaring more than two stories above the deck, Cloud City–Saraceno’s largest such work in his decade-long series of similar pieces–is constructed from a series of pods, or modules, made from a tricky combination of transparent and reflective panels. Tricky because once you get up INSIDE Tomás Saraceno’s Cloud City (more on that in a second), it becomes very difficult to determine which end is up, which way to turn, and whether that next step is going to send you plummeting to the terrace below. It is, of course, totally safe… it just FEELS dangerous.

Argentinian artist Tomas Saraceno created the 16 stainless steel-framed bubbles, accessible via transparent staircases that take visitors on a journey up, with spectacular views of the Manhattan skyline and Central Park.

Tomás Saraceno’s Cloud City will be on view at the Metropolitan Museum of Art New York Roof Garden through November 4. The Met is open Tuesday through Thursday, and Sunday, from 9:30 a.m. to 5:30 p.m., and on Friday and Saturday from 9:30 a.m. to 9:00 p.m. The Roof Garden is closed in inclement weather.
