Manhattan’s most ethereal new attraction might also be the best new spot in the city for engagement photo-shoots. The otherworldly SeaGlass Carousel, nestled in Tiffany & Co. Foundations Woodland Gardens, is now open in Battery Park. Designer George Tsypin, whose work you may remember from the 2014 Sochi Olympics Opening Ceremony, evokes the experience of being underwater with nautilus-shaped canopy and fiberglass fish that glow and spin. A decade in the making, the SeaGlass Carousel is an instant landmark that brings a sense of magic to the city’s waterfront.
