Amaury I of Montfort

Amaury I of Montfort (died 1053) was the second lord of Montfort-l'Amaury in the Île-de-France, succeeding his father Guillaume, who had raised the first wooden castle on the mound that gave the lordship its name. Amaury rebuilt the castle in stone and enclosed the town with fortifications.

Around 1028 he married Bertrade, traditionally assigned to the house of Gometz, who bore him his successor Simon I. He died in 1053.
