The medieval castle of Pouancé is located in Pouancé, Maine-et-Loire, France, at the western border of the old province of Anjou, as a defence against Brittany. Along with the remains of the city walls, it covers a surface of three hectares. It is nicknamed the "second castle of Anjou" because of its size, which is just less that of the castle of Angers. It belongs to the Breton march, facing the Breton castle of Châteaubriant.
