Jaucourt Hotel

The building underwent its first renovation at the end of^{the 17th} century, on the initiative of the Duke of La Feuillade (1673-1725) and based on plans by architect Jules Hardouin-Mansart (1646-1708). Two cylindrical avant-corps remain from this unfinished phase of work, supported by two corbelled trumpets on the lower part of the building. The building was then extensively remodeled during a second phase of construction, carried out from 1733 onwards by the Countess of Jaucourt and her architect Pierre Desmaisons (1711-1795), whose project drawings have been preserved in their entirety. The street facades, including the wrought ironwork, have been listed as historic monuments since 1928.
