Tucked into the 17th-century Hôtel Lantin a few minutes from the Palace of the Dukes, the Musée Magnin is a small national museum with the feel of a private house. Paintings are crowded onto walls floor-to-ceiling in salon style, furniture and ceramics fill the rooms, and the labels are deliberately minimal. The collection of around 2,000 works includes Italian, Dutch, Flemish, and French paintings from the 16th to the 19th century.
It is an antidote to the scale of the Beaux-Arts and a much quieter visit. Allow an hour. Closed Tuesdays; modest admission.
