of Châteaufort


The ramparts, of which only scattered ruins remain, once rose from the crest of a steep hill above a stream that flows into the Yvette.

This was once a place of some importance, chosen in the 10th century or 11th century as the capital of a district under the diocese of Paris. Châteaufort in those days had two churches and a priory: one church for the town, adjoining the priory, and the other for peasants living without the walls, in the hamlet of La Trinité. The first still stands; the second has disappeared.

In the 11th siècle, Gui de Montlhéry was lord of Châteaufort and his son, Hugues de Montlhéry, Grand Seneschal of France, inherited the title in 1112.
In the 12th century, Louis the Fat confiscated the estate from Hugues de Crécy.

In the 13th century, there was a leper colony here1.
In 1480, Louis XI conferred the estate of Châteaufort upon Louis de Brabant.
In 1529, François Ier granted it to Jean de la Barre.
In 1616 it passed to the house of Guise, and on 27 June 1650 into the ownership of Charles d’Escoubleau, Marquis de Sourdis.
Ruined by the Wars of Religion, Châteaufort dwindled into a poor village.
Its residents are known as « Castelfortains ».
