The SeaGlass Carousel, located downtown in Battery Park, pays homage to the New York Aquarium, which was previously located at this location and at one point welcomed 2.5 million visitors annually before closing in 1941. The 2,575 square foot pavilion, modeled after a nautilus, lacks the traditional center pole and is instead turned by four turntables housed below the floor. Each massive fiberglass fish was custom designed and fabricated and the bright and fantastic color-changing LED light fixtures (along with an integrated audio system) is meant to evoke the bioluminescence found deep in the ocean. The results are mesmerizing. Seriously, we could have watched it all night.
