Hôtel des Réservoirs

Hôtel des Réservoirs is a four-story mansion featuring classical French architectural elements from the 18th century, located on rue des Réservoirs. The structure displays typical period characteristics with timeless design in its facade and interior layout.

The mansion was built in 1751 by architect Jean Cailleteau for Madame de Pompadour and featured a covered passageway to Versailles Palace. This private connection reflected the owner's prominent role in royal society of that era.

The building now serves as the departmental office for architecture and heritage of Yvelines, connecting it to ongoing French preservation efforts. Its spaces reflect the relationship between 18th century private residential life and modern awareness of historical protection.

Access may be limited since the building now serves administrative functions rather than operating as a public museum. The exterior facade and surroundings merit a visit to appreciate the architectural details and historic setting.

During the 1870s the building transformed into a prestigious hotel hosting notable visitors including the future King Edward VII and writer Marcel Proust. This period of transformation marked a turning point, making it a gathering place for high society.
