Château de Coucy

The Château de Coucy is a French castle in the commune of Coucy-le-Château-Auffrique, in Picardy, built in the 13th century and renovated by Eugène Viollet-le-Duc in the 19th century.

During its heyday, it was famous for the size of its central tower and the pride of its lords, who adopted the staunchly independent rhyme: roi ne suis, ne prince ne duc ne comte aussi; Je suis le sire de Coucy.
