Motte-and-bailey castle
Audrieu village dates back to Classical Antiquity when it was called "Alderium". There are traces of Gallo-Roman dwellings and a Motte-and-bailey castle. The first lord of the area was Percy, cook for William the Conqueror, who gave it to the descendants of the Duke of Northumberland. In 1593 Audrieu returned to Guillaume de Séran, who married Marguerite de Percy, and whose lordship became a barony in 1615.
