Hippopotamus Fountain

History

This text is part of Parks’ Historical Signs Project and can be found postedwithin the park.

This piece by artist Robert J. Cassilly, Jr. is an interactive play sculpture featuring 14 hippopotami, two of which function as a spray fountain. The fiberglass hippos are part of the spray fountain, and children are invited to play on and around the sculpture. The Playground Project, Inc., a non-profit group that maintains the playground, commissioned the sculptures as part of the 1993 renovation of Riverside Park’s 91st Street Playground, which was subsequently renamed Hippopotamus Playground. Cassilly has designed numerous other pieces of animal art, especially for the St. Louis Zoo, in the city in which he lives.
