In the 1930s philanthropist John D. Rockefeller Jr. and American sculptor George Grey Barnard collaborated to create “an intellectual Coney Island” in Upper Manhattan. The result was the Cloisters, a complex comprised by elements from five medieval cloisters. Sarah Harrison Smith has written a lengthy feature article for the New York Times on New York's medieval museum.
Today the Cloisters houses over 3,000 items collected by Barnard, Rockefeller and other donors, including the marvelous "Unicorn Tapestries, which Rockefeller presented just before the new Cloisters opened in 1938." It also houses many treasure which might have been destroyed if they had remained in the wartorn Europe of World War II.
