Hôtel Camusat, 18th-century private mansion in Troyes, France.

Hôtel Camusat is an early 18th-century mansion at 10 rue Audiffred, built by Jacques Camusat, father of Troyes mayor Nicolas Camusat. It consists of a central block with two wings returning at right angles toward the street. From the street, a tall stone wall with an arched opening inscribed "GRANDE RUE DE COMBUREL" and "DE L'INDUSTRIE" frames dark paneled double doors; a rounded corner tower with a dome-like roof and a round clock in a triangular pediment rise above.

Jacques Camusat commissioned the construction of this residence between 1723 and 1727 for his son, who eventually became mayor of Troyes. The period of building coincided with a time of growing wealth and importance for the trading city.

On the first floor, the left wing holds the former music room, whose walls are covered with full-height 18th-century wood panelling. The central block's rooms keep their own panelling, with overdoor and pier-glass paintings on the theme of love, grey Belgian marble fireplaces and Versailles parquet. The building has housed the Troyes and Aube chamber of commerce since 31 March 1921.

The building is located on rue Audiffred and has been converted into twelve residential apartments ranging from 36 to 122 square meters. While the exterior architecture can be viewed from the street, access to the private interior spaces may be limited.

The main staircase features original curved decorative railings from the 18th century paired with Versailles-style flooring containing black decorative stones. This level of craftsmanship detail is uncommon to find so intact in residential buildings today.
