Classic Playground entrance at Riverside Park, 76th Street, lower level. So much work was done in the construction of Riverside Park, especially the southernmost two miles of it, that there is not much record of each and every playground, path, staircase, and other feature, but this is definitely part of the original 1934-37 construction (see 1937 photo) similar to the Boat Basin Rotunda three blocks to the north: concrete construction faced with fieldstone, and the playground itself is typical 1930s.
