Paley Park is a pocket park in Midtown Manhattan, NYC. It is often cited as one of the finest urban spaces in the United States. Key to its success is a 20-foot high waterfall spanning the entire back of the park. The waterfall creates a backdrop of grey noise to mask the sounds of the city. The park is surrounded by walls on three sides and is open to the street on the fourth side, facing the street. The walls are covered in ivy, and the overhead canopy formed by locust trees adds serenity.
