Frick Collection

Henry Clay Frick’s personal art collection is displayed in what was once his Upper East Side mansion. The elegant rooms are filled with European sculpture, decorative arts, and paintings by old masters. There are only a few of these grand mansions left in the city, so it’s a rare taste of old New York. The first Friday of the month is free. No kids under 10 are allowed into the museum, so if you go on a weekday, you don’t need to worry about field trips overtaking the galleries.
