Set in a lovely park overlooking the Hudson River, the Cloisters houses the Met’s medieval art and architecture collections. A path winds through the peaceful grounds to a castle that seems to have survived from the Middle Ages. (It was built less than 100 years ago, using material from five medieval French cloisters.) Be sure to check out the famous Unicorn Tapestries, the 12th-century Fuentidueña Chapel and the Annunciation Triptych by Robert Campin.
