Origin and history

The castle of Sainte-Mère is an emblematic example of the Gasconic castral architecture of the late 13th century. Built around 1277, probably by the bishop of Lectoure Géraud II de Montlezun, it is distinguished by its quadrangular structure, its two square towers aligned with the north wall, and its absence of defensive devices marked (fossed, pregnant, or mâchicoulis). Although without proven military functions, its blind ground floor and residential floors equipped with chimneys and sinks reflect a vocation above all seigneurial and residential. The neat masonry, the cruciform archeries, and a window with spears added in the 15th century testify to its limited evolution over the centuries.

The castle was the residence of the bishops of Lectoure until the Revolution, without ever playing a confirmed defensive role, contrary to an old hypothesis linking these buildings to a border line between French and English possessions. This theory, popularized in the 19th century by Philippe Lauzun but disputed since the 1970s, is not supported by any proven historical conflict. The monument, sold as a national property after 1789, suffered degradations (breaks to recover stones) but retained most of its structure. Ranked in 1943 and then in 1977, it still dominates the village of Sainte-Mère, 10 km north of Lectoure, as a vestige of a preserved medieval episcopal heritage.

The building is characterized by its central body of 18 m by 11 m, flanked by two towers with dissymmetric proportions (26 m and 20 m high). The original access, located on the first floor via a mobile staircase, and the absence of interior split walls underline a design focused on comfort rather than defense. A fire around 1600 is mentioned by Gilles Séraphin, but the material traces of this event remain undetermined. Today in ruins (without roof or interior floors), the castle offers a rare testimony of the gascon castles, a civil architectural type marked by a slender silhouette and integration into the village fabric, as evidenced by the remains of an adjacent village enclosure, partially reused for the local church.

The building of the castle coincides with the apogee of the episcopal power at Lectoure, where Géraud II de Montlezun also carried out important works at the cathedral, including the nave in dogives. This link between religious and seigneurial heritage illustrates the multifaceted role of medieval bishops, both builders and political actors. The castle of Sainte-Mère, without a permanent garrison, probably served as a relay between Lectoure and other episcopal domains, as suggested by its visual proximity to the castle of Rouillac in Gimbrède, although there is no evidence to confirm the existence of an underground connecting them.

The modifications made to the castle are limited to minor developments, such as the 15th century door window, and post-revolutionary degradation. Its classification as historical monuments in 1977 preserved a remarkably intact masonry, despite the absence of cover and interior furnishings. The wooden sturds and the round path, hypothetical, are based on the presence of bolts and ravens, while the village tower, integrated into the church, recalls the old communal enclosure. This site, studied by scholars such as Philippe Lauzun and Jacques Gardelles, remains a subject of study for the history of seigneurial habitat in Gascony.

Unlike classical castles, the castle of Sainte-Mère embodies an architecture of prestige and pacified territorial control, typical of a region where border conflicts were rare despite the proximity of English possessions. Its current state of "stable" ruin makes it an educational example to understand the Gascon rooms, these aristocratic or high episcopal residences, often mistakenly confused with fortresses. The local legend and Romance interpretations have long masked its first vocation: a place of life and episcopal administration, far from the battlefield.
