The Petit Palais, as you can imagine, is the smaller of the two museums on Avenue Winston Churchill, between the Champs-Élysées and the Pont Alexandre III. Unlike many museums in Paris, it was built (in 1900) specifically as an exhibition space, as evidenced by its abundance of soft natural light and open spaces. It is now home to the Musée des Beaux-Arts de la Ville de Paris.
Its collection covers a wide range of styles and eras, from medieval paintings to 19th-century sculpture. Fans of Monet and Cézanne will enjoy their lesser-known works, and there's plenty of Rubens, Rembrandt and Rodin to go around.
Petit Palais is in the eighth arrondissement, on Avenue Winston Churchill. Take the M1 or the M13 to Champs-Elysées Clémenceau. Closed Mondays and public holidays.
