Hôtel Mégret de Sérilly, Private mansion in Le Marais, Paris, France

Hotel Megret de Serilly is a private mansion with brick and stone facades in Le Marais. The main building is flanked by two service wings surrounding a central courtyard, with regularly spaced windows defining its appearance.

Nicolas Malebranche, a financier and secretary to the king, had the house built between 1618 and 1621 by Jean Thiriot, who had just finished the neighbouring Hôtel d'Hozier. In 1686 it passed to Charles du Tillet, marquis de La Bussière, whose family altered it. Antoine Jean-François Mégret de Sérilly, its owner from 1776, gave it his name and had it redecorated by Pierre-Noël Rousset before being guillotined during the Terror.

The building takes its name from Antoine Jean-François Mégret de Sérilly, who bought it in 1776 and had it redecorated by architect Pierre-Noël Rousset. In 1778 a boudoir was fitted out for his wife, with wood paneling by Jules-Antoine Rousseau, a fireplace carved by Philippe-Laurent Roland and a painted ceiling by Jean-Jacques Lagrenée. Sérilly was guillotined during the Terror.

The mansion stands at 106 Rue Vieille-du-Temple, its street front rebuilt in the 18th century while the brick-and-stone courtyard and garden elevations keep their 1618 layout. It remains a private residence, so the entrance and courtyard are not open to visitors; the listed facades and roofs, protected since 1961, are seen from the street.

Two ornate rooms from the late 18th century were removed from the house and now reside in different countries. One boudoir is displayed in London while another salon is located in Newport, Rhode Island.
