Roy ne suis, ne Prince, ne Duc, ne Comte aussi. Je suis le Sire de Coucy, so went the proud motto of the man who built this imposing fortress. Within its medieval walls, Coucy stretches over a promontory that dominates the Oise and Ailette valleys, occupying an impressive defensive position. In summer the inhabitants honour the history of the district with the "Coucy à la Merveille" festival, one of the region's most charming medieval shows. Enjoy the view from the platform of the Porte de Soissons (13C).
