Castle closed to the public, but it is bordered by a shared road limited to 30 km/h which is very pleasant.

This impressive 18th-century château, surrounded by lush gardens and a serene moat, offers a glimpse into the opulent lifestyle of the French aristocracy. You can explore the beautifully preserved interior, admire the intricate architectural details, and stroll through the peaceful grounds.

At the end of the 12th century, the estate was allegedly owned by a knight Gautier, "lord of Mesnil", and a liege man of King Philippe Auguste. In the 15th century, the property passed into the hands of the Karnazet family, who passed it down through several generations, until 1455, when Jean de Vaillant took over the reins of the estate. The Mesnil chapel was commissioned by Renée Sabathier, wife of Guillaume Hérouard, secretary of the King's chamber, in 1611. She was buried there in 1616.

Beautiful view of this castle from the beginning of the 17th century. Its dovecote is one of the largest in Ile de France.
