There are so many things to enjoy about the Cloisters. It is quite compact compared to other museums so you will be able to take it all in. The collections are stunning, especially the tapestries, but every area has interesting and historical architectural details, furniture, fixtures, artwork. The building itself is very atmospheric and features grand spaces, with collections from ecclesiastical ancient buildings. It is almost like travelling to medieval Europe - including the actual Cloisters courtyard gardens, another wonderful feature. Don't miss the view from the terrace over the Hudson! The Cloisters surpassed all of my expectations.
