Toulouse boasts more than fifty hôtels particuliers, private mansions built for the city's nobles and aristocrats during the 16th and 17th centuries. Among the finest is the Hôtel d'Assézat, built for a woad merchant in 1555. It's now home to the Fondation Bemberg , which owns a fine collection of paintings, sculpture and objets d'art; the first floor is mainly devoted to the Renaissance, while Impressionism, pointillism and other 20th-century movements occupy the upper floor. Guided tours depart daily at 3.30pm.
