Origin and history

The Château de Parthenay is a former castle whose remains, classified as historical monuments since 1994, are located in the Deux-Sèvres department. Built from 1227, it was modified in the 15th century before being shaved in 1830. Its ruins, including a round tower and portions of ramparts, still bear witness to its strategic importance, controlling the axes between Poitiers, Nantes, Thouars and Niort.

The site, occupied from the Xth–XIIth centuries, was fortified by the archbishops, influential Poitevin lords. The castle, composed of six towers connected by courtines, housed seigneurial buildings, a castral chapel, and outbuildings. He played a key role in princely and royal seats, reflecting his importance from the twelfth to the fifteenth century.

Current remains include defensive elements such as the castle tower, Harcourt Tower, and bastilles. The Porte Saint-Jacques, with almond towers and mâchicoulis, as well as the ramparts overlooking the Thouet, recall its complex protection system. A second enclosure, visible rue du Moulin and boulevard de la Meilleraye, strengthened the fortress.

The castle was integrated into a closed village, with a prosperous village in the valley. Its fortified bridge, crossing the Thouet, also served as a pilgrimage route (vaux Saint-Jacques). The remains, owned by the commune, have been protected since 1994, marking their heritage value.

Historical sources, such as Châteaux en Poitou-Charentes (2006) and the Mérimée archives, confirm its military role and its architectural evolution. The Archbishops, as sponsors, left a lasting mark on this emblematic site of the Poitou.
