SeaGlass Carousel, Aquatic-themed carousel at The Battery, United States

The SeaGlass Carousel is a circular pavilion in the Battery with a tilted roof of gray panels rising to a glass-rimmed cupola. Its cylindrical facade is glazed in curved glass panels with dark vertical mullions, backed by white vertical supports. Inside, thirty fish figures, including Siamese fighting fish, rotate, rise and descend on four separate platforms. A dark panel by the entrance reads "Aquademy" and "SeaGlass".

The carousel opened on August 20, 2015, after nearly a decade of design and construction by the architecture firm WXY and set designer George Tsypin. Its $16 million cost was half funded by the city and the Lower Manhattan Development Corporation, and the project was led by Warrie Price, founding president of the Battery Conservancy. It was seen as a sign of recovery after Hurricane Sandy damaged the park in 2012.

Set designer George Tsypin combined theatrical elements with classical music compositions by Mozart, Debussy, and other composers to create an underwater experience.

The pavilion sits in the Battery at Manhattan's southern tip, near the Staten Island Ferry's Whitehall Terminal and Castle Clinton. Riders board the fish figures from the open entrance; the machinery is under the floor, so the deck stays clear. A ride lasts three and a half minutes.

Unlike traditional carousels, this ride has no center pole because electric motors hidden beneath the floor power the fish figures. This hidden mechanical system allows the spinning and lifting movements to happen without any visible support.
