Hôtel Désandrouin, Private mansion in fortified city of Boulogne-sur-Mer, France.
The Hôtel Désandrouin features a neoclassical stone facade with two levels, marble base foundation, colossal pilasters, and a pediment displaying the original owner's coat of arms.
The mansion served as headquarters for Napoleon Bonaparte's Grande Armée in 1803, hosting the emperor multiple times including his 1810 stay with Empress Marie-Louise of Austria.
The first floor maintains its original neoclassical decorations, including Napoleon's preserved workspace and bedroom, furnished according to the Empire period style.
The building opens its doors during heritage days and summer guided tours, allowing visitors to explore the historical interiors and architectural elements.
The mansion changed its name to Imperial Palace following Napoleon's stays, marking its transformation from a private residence to a symbol of French imperial power.
