Hôtel de Mercy-Argenteau

Hôtel de Mercy-Argenteau stands on Boulevard Montmartre in Paris, where a discreet facade conceals an eighteenth-century mansion. Firmin Perlin built it in 1778 for banker Jean-Joseph de Laborde, creating an early boulevard structure among later buildings. The preserved mansion stands alongside the Hôtel de Montholon, another surviving historic building on the boulevard.

During the French Revolution, the property lost much of its garden and its outbuildings. Early nineteenth-century additions raised the building and created apartments linked by long corridors beneath skylights. Two staircases at opposite ends organise those upper floors, while a banquet hall above the courtyard dates from 1890. Charles Garnier is associated with that hall, and DTACC later restructured the building while preserving listed first-floor elements.

Inside, a monumental vestibule, grand staircase and Louis XVI salon retain Corinthian columns. Composers Boieldieu and Rossini lived here, while the École des Arts Joaillers presents temporary exhibitions on jewellery.
