Hôtel d'Haussonville, Renaissance mansion in old town Nancy, France.

The Hôtel d'Haussonville is a 16th-century Renaissance mansion at the corner of rue Monseigneur-Trouillet and rue Saint-Michel in Nancy's Ville-vieille. Its pale beige stone facades have tall mullioned windows, a chamfered corner framed by carved pilasters, and a steep grey slate roof with a pyramidal corner turret, a dormer and two chimneys. Behind the sober street front, a courtyard opens onto rue Monseigneur-Trouillet, with two carved galleries, one Gothic in inspiration and one Renaissance, and a Neptune fountain.

Jean d'Haussonville, sénéchal of Lorraine, built the mansion between 1528 and 1543. The Haussonville family sold it in the 18th century; after a series of owners, Joseph d'Haussonville bought it back between 1849 and 1851. His son Paul-Gabriel died in 1924 and the four heirs sold it again. A decree of 6 December 1984 classified the facades and roofs on the two streets and courtyards, and inscribed the ground-floor salon and dining room and the first-floor small salon with their 18th-century decor.

The courtyard holds two carved galleries, one Gothic in inspiration and the other Renaissance, plus a fountain of Neptune. The name comes from Jean d'Haussonville, sénéchal de Lorraine, who built the mansion between 1528 and 1543. The ground-floor salon and dining room and the first-floor small salon keep their 18th-century decoration.

The mansion stands at the corner of rue Monseigneur-Trouillet and rue Saint-Michel in Ville-vieille. The courtyard opens onto rue Monseigneur-Trouillet, so it can be seen from the street even without entering the building. The facades and roofs on both streets and both courtyards are protected, while the verandas are excluded from the listing.

The courtyard's Neptune fountain and the two galleries, one Gothic and one Renaissance, are easy to miss from the street: the sober facades on rue Saint-Michel conceal the court, which opens onto rue Monseigneur-Trouillet. The 1984 designation covers the facades and roofs on both streets and both courtyards, excluding the verandas.
