"A family of great art collectors—the Marquesses of Hertford and Sir Richard Wallace—accumulated art by some of the world's most renowned artists of the 14th to the 19th centuries. Work by Titian, Rembrandt, Rubens, Fragonard, and Watteau is all displayed in their former home. Major pluses: Admission is free and the cafe is stunning. "
