This spectacular art collection sits in a mansion built by prickly steel magnate Henry Clay Frick, one of the many such residences that made up Millionaires’ Row. The museum has 12 splendid rooms that display masterpieces by Titian, Vermeer, Gilbert Stuart, El Greco and Goya. The Oval Room is graced by Jean-Antoine Houdon’s stunning figure ‘Diana the Huntress.’

This museum is a treat for a number of reasons. One, it resides in a lovely, rambling beaux arts structure built from 1913 to 14 by Carrère and Hastings. Two, it is generally not crowded. And, three, it feels refreshingly intimate, with a trickling indoor courtyard fountain and gardens that can be explored on warmer days. A demure new Portico Gallery, opened in 2011, displays decorative works and sculpture.

A worthwhile audio tour (available in several languages) is included in the price of admission. Classical music fans will enjoy the frequent piano and violin concerts that take place on Sundays.
