Union Square Park Playground (New York, N.Y.)
The 15,000 square-foot Union Square Park Playground opened at the end of 2009 and looks nothing like any other play space in New York City. It is divided into three sections, all outdoors, and each featuring different play equipment for different age groups. The playground combines traditional play equipment such as swings, climbing structures, sand pits with features such as a giant geodesic silver dome, spinning rides -- one spinning teacup is called The Nest -- and a water area. The new park also has gardens and greenery, and Union Square is home to the largest green market in NYC.
