As such, there are also many high-end museums along Fifth Avenue called “Museum Mile.” The elegant Frick Collection houses a smattering of rare paintings and sculptures. The Morgan Library and Museum turned Pierpont Morgan’s mansion into a world-class research center. The splendid Metropolitan Museum of Art and Guggenheim Museum are further up. (The latter is dedicated to contemporary artwork.) The Whitney Museum emphasizes living American artists, while the Cooper Hewitt Museum thrusts design and architecture into the spotlight. The Museo del Barrio, Jewish Museum, and the Museum of the City of New York all celebrate the local ethnic diversity.
