Origin and history
The Hotel de Montmorency-Fosseux, located at 2 & 4 rue de Tournon in the 6th arrondissement of Paris, is a mansion built in the 4th quarter of the 18th century. It belongs to a series of hotels linked to the house of Montmorency, an influential aristocratic family. The building has been listed as a Historic Monument since 1986, with protected elements such as the monumental door, facades, vestibule, and several apartments.
The hotel is associated with several historical owners, including François de Montmorency-Fosseux (1614-1684), Marquis de Bois-Ruffin, and his descendants. The identified contractor is Lemonnier. The protected common and private areas include emblematic spaces such as the stairwell and richly decorated apartments, reflecting the prestige of its occupants.
Unlike other hotels in Montmorency mentioned in the sources (such as those on Sainte-Avoye, Capucines or Cherche-Midi streets), this hotel is not linked to major historical events such as destruction or radical transformations. It retains a significant part of its original architecture, although its current use is not specified in available sources.
The available sources (Wikipedia, Monumentum) highlight its heritage importance, in particular by its classification that protects interior and exterior elements. The exact location is confirmed by the Merimée bases and GPS coordinates, with an accuracy considered "passable" (level 5/10).
