Origin and history

The castle of Mareil-le-Guyon, built in the seventeenth century, is located in the municipality of the same name, in the department of Yvelines. Its history is linked to influential families in the history of France, including the lords of Mareil, involved from the thirteenth century in major events such as the Albigois Crusade.

During the Hundred Years' War, the castle of Mareil was attacked by the English. After the Wars of Religion, at the end of the 16th century, the moat was filled and the castle rebuilt, forming the base of the current building. In the 18th century, it was enlarged with lateral wings to accommodate the family of Marquis Chaumont de La Galaizière.

Under Louis XIV, Nicolas Menueau sold the castle to settle his debts. In 1719 the Chaumont de La Galaizière family became its owner until the Revolution. Antoine-Martin Chaumont de La Galaizière, Marquis and Chancellor of King Stanislas I, played a key political role. A monumental painting, commissioned 40 years after the facts, represented Stanislas receiving the Chancellor's allegiance.

During the Revolution, the castle was confiscated and returned to the Chaumont family in 1794. In the 19th century, he passed into the hands of several women of the nobility, including Baroness Le Peletier of Aunay and Duchess of Avaray, before being acquired by banker David-Weill. Since 2007, it has hosted business seminars.
