Hôtel d'Aumont, Private mansion in Marais, France.

The Hôtel d'Aumont is a former hôtel particulier at 7, rue de Jouy, in the 4th arrondissement of Paris, built entre cour et jardin. Its garden front, shown here, has a long pale stone facade with a steep slate roof pierced by pedimented dormers; slightly projecting pavilions flank the central three bays, and the windows carry wrought-iron balconies. Since 1959 it has housed the tribunal administratif de Paris.

Michel-Antoine Scarron assembled three adjoining properties between 1619 and 1630 and had the old building replaced; the corps de logis was begun in 1631 and the structure completed in 1648, with Michel Villedo as mason. François Mansart later added a grand staircase in the right wing and Charles Le Brun and Simon Vouet painted the decors. Sold in 1756, it housed the mairie from 1802 to 1824, then boarders of the Lycée Charlemagne, and from 1859 the Pharmacie centrale de France. The City of Paris bought it in 1938; the tribunal administratif moved in in 1959.

The hôtel's name comes from the dukes of Aumont, who lived here in succession until 1742; Louis-Marie-Augustin d'Aumont sold it in 1756. Since 1959 it has housed the tribunal administratif de Paris, and the Cabinet neuf, added in the early 18th century, now serves as the office of the tribunal's president.

The mansion is located on rue de Jouy near the Pont Marie metro station, making it easy to reach. Access to the interior is limited since it functions as a courthouse, but the facade is visible from the street and worth viewing during a walk through the neighborhood.

In 2003, the remains of Queen Arégonde were found in a strongbox at the Hôtel d'Aumont, where Michel Fleury, vice-president of the Commission du Vieux Paris, had kept an office until the 1970s. The Merovingian queen's relics had been stored there rather than in a museum.
