The International Sculpture Garden (in progress) is located at Penn's Landing, along the Delaware River between Chestnut and Spruce Streets. The Fairmount Park Art Association conceived the International Sculpture Garden in the 1960s. The garden would display ancient and historic artworks to demonstrate and celebrate the impact of other cultures on the American experience. "Each individual piece," the Art Association noted, "should not only be typical of that nation's heritage but should also be of the highest quality." The Art Association acquired and installed the garden's sculpture collection over several years and today continues to own and maintain the works. Dedicated in 1976 as part of the celebration of the U.S. Bicentennial in Philadelphia, the waterfront site symbolizes the international nature of the port and the diversity of human achievement through time.
