The Château de Challeau refers to two châteaux in the neighbouring communes of Dormelles and Villecerf, near Fontainebleau in the department of Seine et Marne, France.
The first Château de Challeau was a fortified building built in the 11th century to 12th century. It has a 6m high and 1.3m thick curtain wall which surrounds an area approximately 30m by 24m, with rounded watchtowers at the corners. Unusually, it did not have a central keep, and internal buildings seem to have been limited to temporary shelters. It was modified in the 15th century, during the Hundred Years War. After the French Revolution, it was confiscated as a bien national and sold to Guillot de Blancheville. It was recovered by the descendants of its original owners in 1937, and restored.
