The building is located along prestigious Central Park West and was built in 1910, it opened in 1911.  Cast in the Arts and Crafts style, a rarity for New York City, Harperly Hall was designed by Henry W. Wilkinson.

Central Park Casino: The Central Park Casino, originally the Ladies Refreshment Salon, was a restaurant near East 72nd Street, in Central Park in New York City.  The name of the building came from the Italian for "little house"; the Casino itself was not a gambling business.  Built in 1864, the restaurant was once intended for unaccompanied female visitors to Central Park, but was soon patronized by both men and women.  While the building that housed the Casino belonged to the City of New York, the City often leased the Casino to independent operators.  Mayor Jimmy Walker exercised this power in 1929 by terminating the lease of C.F. Zittel, allowing Walker's friend, Sidney Solomon, to transform the Casino into one of New York's most expensive nightclubs.  Besides entertaining elite guests in the restaurant, Walker had an office in the Casino and conducted city administration there while meeting with political cronies.

Diana Ross Playground: The Diana Ross Playground is located in New York City's Central Park, inside the park at West 81st Street and Central Park West.

However, when a thunderstorm during the first (and only scheduled) concert destroyed all of its memorabilia/merchandise, the performance did not prove profitable, and Ms. Ross used personal resources to fund the project.  Groundbreaking took place in September, 1986, with both Ross and then-Mayor Ed Koch present.  Ross reportedly called the event "one of the most fulfilling aspects of [her] life and career."
