Imagine a massive stone castle rising above the banks of the Sèvre Niortaise River. This is the Donjon of Niort — an outstanding monument of medieval architecture located in the city of Niort. This unique structure in France is a rare example of a twin Romanesque keep, consisting of two majestic square towers connected by walkways.

The Donjon is more than just a historical monument; it is a true symbol of the region. The total length of the fortress is about 70 meters, and the height of the southern tower reaches 28 meters. Today, it houses a museum, where visitors can experience the history of Niort through rich exhibitions dedicated to archaeology and local traditions.
This site is striking in its power: walls up to three meters thick at the base and stern buttresses serve as reminders of the fortress's former defensive significance. The architectural purity of the Romanesque style makes the Donjon of Niort one of the most significant landmarks in the Nouvelle-Aquitaine region.
