Built at the beginning of the 17th century, the castle has known various owners, from Nicolas de Harlay, Minister of Henri IV to the Marshal of Empire Alexandre Berthier, Prince of Wagram. Fully furnished, it has retained much of the heritage of the time of Napoleon I: armchairs, paintings, decorations of all kinds as well as rare and original pieces. Other furniture, older, are also present in the rooms of the castle.
The original decoration of the Louis XIII dining room, consisting of wall paintings, offers a beautiful testimony of the seventeenth century. The castle’s library contains more than 3,000 military, scientific and historical works, as well as maps and battle plans.
The castle of Grosbois is inscribed since 1933 on the list of historical monuments. Since 1962, it belongs to the Société d'Encouragement à l'Elevage du Cheval Français, which ensures the conservation and enhancement of this exceptional heritage.
