History

Mr. E.W. Clark, a prominent Philadelphian, purchased five acres of former quarry land with the intention of making it a playground after a young child drowned in the quarry. He hired George T. Pearson, a well-known architect to design the main building known originally as the Quarry Playground House, completed in 1910. Mr. Clark's wife named the playground Happy Hollow.

The Clarks donated the state-of-the-art facility, to the Playground Association of Philadelphia.The opening of the Happy Hollow Playground was announced April 29, 1911. It is the city's oldest playground.
