Here, 140 chronological rooms depict the history of Paris, from pre-Roman Gaul to the 20th century. Built in 1548 and transformed by Mansart in 1660, this fine house became a museum in 1866, when Haussmann persuaded the city to preserve its beautiful interiors. Original 16th-century rooms house Renaissance collections, with portraits by Clouet and furniture and pictures relating to the Wars of Religion. The first floor covers the period up to 1789, with furniture and paintings displayed in restored, period interiors; neighbouring Hôtel Le Peletier de St-Fargeau covers the period from 1789 onwards. Displays relating to 1789 detail that year's convoluted politics and bloodshed, with prints and memorabilia, including a chunk of the Bastille. There are items belonging to Napoleon, a cradle given by the city to Napoleon III, and a reconstruction of Proust's cork-lined bedroom.
