Château d'Hennemont

The Château d'Hennemont is an early 20th-century manor house sitting at the highest point between the Mareil-Marly and Saint-Germain-en-Laye forests. Its distinctive two-tone facade of brick and limestone displays architectural details characteristic of the Belle-Époque period.

The manor was built in 1907 for pharmacist Henri Canonne on the site of a medieval priory that was destroyed in 1346 during the Hundred Years' War. The religious community that once thrived there was completely erased from the area's memory.

The main reception room displays decorative elements typical of early 20th-century French upper-class homes, with double doors that open directly to the garden. This layout reflects how residents connected indoor and outdoor living spaces in that period.

The building has been integrated into the Lycée International de Saint-Germain-en-Laye since 1951 and now functions as a school facility. Visitors should expect limited access to the historical areas and grounds due to its current educational use.

The main staircase is a spiral stone structure inspired by Leonardo da Vinci's design at Château de Chambord. This architectural reference connects a private French home to Renaissance innovation that visitors might otherwise overlook.
