Hôtel Pierrard, Private mansion in 4th arrondissement of Paris, France

Hôtel Pierrard is a private mansion on the west side of Place des Vosges in Paris, with a stone facade, tall windows, and steep slate roofs. Its covered arcade runs along the ground floor, and a vaulted passage opens toward an inner courtyard.

The mansion dates from the early 17th century and was first owned by Pierre Fougeu-Descures, who rented it to Marion Delorme from 1639 to 1648. A branch of the Colbert family later took it over, and the facade and arcade gained official protection in 1954.

The mansion's name comes from the Pierrard family, though it is also called hôtel Colbert-de-Villacerf, de Creil or de Voisenon after later owners. It stands at 11 place des Vosges and 12 rue de Turenne, on the west side between the hôtels de Chaulnes and Dyel des Hameaux. The arcade columns at the entrance carry the inscription "NICOLAS 1764", left by the writer Nicolas Edme Restif de La Bretonne.

The building is a private condominium at 11 place des Vosges, with its entrance at 12 rue de Turenne; the interior is not open to visitors and no tours are offered. The facade, roofs and vaulted gallery facing the square have been classified as monuments historiques since 1954, so they are seen from the public square and the arcade. The arcade columns at ground level are where the "NICOLAS 1764" inscription can be found.

On one of the arcade columns, you can still see a carved line reading “NICOLAS 1764”, left by the writer Nicolas Edme Restif de La Bretonne. It is thought to be the oldest piece of graffiti in Paris, hidden in plain sight for anyone who knows where to look.
