The medieval castle of Pouancé is located in Pouancé, at the western border of the old province of Anjou, where it was built 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 than that of the castle of Angers. It belongs to the Breton march, facing the Breton castle of Châteaubriant.
Situated in a location which was fortified in the 11th century, the castle was built between the 12th and 15th centuries. Besieged several times during the Hundred Years' War, it became a strategic fortress at the end of the 15th century, during the Mad War. Ruined during the 16th century and completely abandoned since the 18th, it was saved from destruction when Louis Bessière, an inhabitant of Pouancé, decided to restore the building in the 1960s. The castle is now owned by the town of Pouancé and is open to visitors during the summer months.
The castle has been listed as a monument historique since 7 July 1926. Despite volunteers and amateur excavations over 40 years, little is known about the structure of the castle, due to a lack of deep archaeological surveys.
References:Ehrenbreitstein Fortress was built as the backbone of the regional fortification system, Festung Koblenz, by Prussia between 1817 and 1832 and guarded the middle Rhine region, an area that had been invaded by French troops repeatedly before. The fortress was never attacked.
Early fortifications at the site can be dated back to about 1000 BC. At about AD 1000 Ehrenbert erected a castle. The Archbishops of Trier expanded it with a supporting castle Burg Helferstein and guarded the Holy Tunic in it from 1657 to 1794. Successive Archbishops used the castle's strategic importance to barter between contending powers; thus in 1672 at the outset of war between France and Germany the Archbishop refused requests both from the envoys of Louis XIV and from Brandenburg's Ambassador, Christoph Caspar von Blumenthal, to permit the passage of troops across the Rhine.
