the Cloisters, museum of medieval European art, in Fort Tryon Park, New York City, overlooking the Hudson River. A branch of the Metropolitan Museum of Art, it was opened to the public in May, 1938. Designed by architect Charles Collens (1873–1956), the building includes elements from five French cloisters, a 12th-century Romanesque chapel, and a chapter house; three of the reconstructed cloisters enclose authentic medieval gardens. The core of the collection the museum houses consists of several hundred examples of medieval painting, sculpture, and other forms of art gathered in France by George Grey Barnard. This collection was bought by John D. Rockefeller, Jr. (see under Rockefeller, John Davison), in 1925, and presented to the Metropolitan Museum. Later additions include a series of 15th-century tapestries, Hunt of the Unicorn; a tapestry series of the 14th cent., The Nine Heroes; the famous Mérode Altarpiece by Robert Campin; the Bury St. Edmunds ivory crucifix; and Les Belles Heures de Jean, Duc de Berry, an early 15th-century illuminated book of hours. The holdings also include outstanding examples of stained glass, ritual objects, metalwork, and enamels.
