Free (Suggested) Admission on Thursdays at the The Met Cloisters - see INFO below. Much of the sculpture at The Met Cloisters was acquired by George Grey Barnard (1863–1938), a prominent American sculptor, and an avid collector and dealer of medieval art. Barnard opened his original Cloisters on Fort Washington Avenue to the public in 1914. Through the generosity of John D. Rockefeller, Jr. (1874–1960), the Museum acquired Barnard's Cloisters and most of its contents in 1925. Early on, it was clear that a new, larger building would be needed to display the collection in a more scholarly fashion. Rockefeller donated to New York City, and financed the conversion of, some 56 acres of land just north of Barnard's museum, which became Fort Tryon Park—approximately four acres of which was destined as the site for the new museum.
