This magnificent 18th-century mansion houses a sumptuous staircase with a banister designed by Jean Lamour and a trompe l'oeil painting above it by Barilli. Don't hesitate to push open the door to the stairwell if the heritage inventory that occupies the premises is open! A courtyard typical of mansions of this era is adorned with a Neptune fountain. It is currently the headquarters of the Inventory of Historical Monuments of the DRAC of Lorraine. Exterior visits only.
