Built between 1777 and 1780 as a private mansion, the Hôtel Desandrouin (also known as the Palais Impérial) was later used by Napoléon in 1803, 1810 and 1811 as an operational base. Check with the tourist office for infrequent tours in English and French between June and August. It's otherwise closed to the public.
