Origin and history

The castle of Xaintrailles, located in the department of Lot-et-Garonne in New Aquitaine, finds its origins in the 13th century with the construction of a first dungeon and a medieval courtyard. Originally held by three co-teachers of the Xaintrailles family, this fortress was first mentioned in 1259. The remains of this era include the dungeon, the slopes of the south and west walls, as well as defensive elements characteristic of medieval castral architecture.

In the 15th century, Jean Poton de Xaintrailles, a companion of Jeanne d'Arc's weapons, and his successors (Bernard de Lamothe and Antoine de Chamborel) undertook important works: construction of two towers, a body of northern houses, and piercing windows in the dungeon. These changes reflect the evolution of residential and defensive needs, marking the transition from the Middle Ages to the Renaissance. The castle then passed to the families of Montesquiou (1570) and then Lau de Lusignan (1724), who made major improvements in the 17th and 18th centuries, such as filling the ditches and creating a western access.

The sixteenth and eighteenth centuries saw the addition of remarkable architectural elements: fan turrets on the south elevation, U staircase, and vestibule. In 1824, part of the castle collapsed, and partial restorations were carried out in 1843 by architect Gustave Bourières. The estate, including terraced gardens, star wood and a menagerie, was listed as a historic monument in 1840, and its park and outbuildings were registered in 2011. Today the private property, the castle bears witness to seven centuries of history, mixing medieval heritage and Renaissance transformations.

Historical sources, including the works of Georges Tholin and Fernand Lamy, highlight the castle's strategic role in the feudality of the Agen. Its hybrid architecture — medieval dungeon, Renaissance houses, and classical arrangements — makes it a rare example of constructive continuity. The archives also mention its use as a model mansion, cited by Eugène Viollet-le-Duc for his late Middle Ages style.

The castle is inseparable from Jean Poton de Xaintrailles, a major military figure of the Hundred Years' War, whose legacy still permeates the site. The successive modifications (fossed, drawbridge, kitchens) illustrate the adaptation of the building to social and technological developments, from the medieval fortress to the aristocratic residence of the Lights. Its early classification in 1840 reflects its heritage importance, reinforced by the subsequent protections of the estate and its landscape approaches.

Archaeological studies and local journals (such as the Revue de l'Agenais) document the construction phases and uses of the castle, especially during the Revolution. The gardens, renovated in the 19th century in an English style, complete this historical painting, where defence, seigneurial habitat and landscape aesthetics are mixed. The castle of Xaintrailles thus remains a key milestone of the Aquitaine Castral heritage, at the crossroads of periods and architectural influences.
