Hôtel de Tresmes, Private mansion on Place des Vosges, Paris, France

Hôtel de Tresmes is a private mansion at 26 place des Vosges, on the north side of the square between the hôtels de Vitry and d'Espinoy. Its red brick facade is framed by light stone quoins and bands, with tall white-framed windows, small iron balconies, dormer windows with arched pediments in the slate roof, and tall brick chimneys with stone caps.

The residence emerged as part of the transformation of Place des Vosges in the early 1600s, when the square became a statement of royal vision for Parisian architecture. Modifications to the building during the 1600s, particularly work on the rear facade, reflect how owners continuously adapted their homes to changing tastes and needs.

The building is also known as hôtel de Gourgues, a name recalling a later owner. In the 18th century it was rented out rather than occupied by its owners, and its courtyard buildings were altered again in the 19th century, when the mansion became a condominium.

The mansion stands at 26 place des Vosges, on the north side of the square between the Hôtel de Vitry and the Hôtel d'Espinoy, in the 3rd arrondissement. It is a private condominium, so only the facade can be seen from the square; the rear facade and courtyard, reworked by François Mansart, are not open to visitors.

Wealthy owners like Bernard Potier commissioned the renowned architect François Mansart to redesign the rear facade, demonstrating how the square's richest residents hired the finest architects of their era. This less visible work on the back of the building shows that even hidden spaces received artistic attention and investment.
