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.
