Comminges in the Middle Ages
The County of Comminges
In the Middle Ages, Comminges formed a powerful and relatively autonomous county, centered around the town of Saint-Bertrand-de-Comminges.
The county’s origin dates back to between the 9th and 10th centuries. After the fall of the Carolingian Empire, the region was structured around a feudal county: the County of Comminges.
The territory largely corresponds to the ancient Gallo-Roman city of Lugdunum Convenarum (present-day Saint-Bertrand).
Local noble families gradually took control of the territory.
The power of the Frankish kings was distant: the counts governed almost independently.
Comminges held a strategic position, bordering the Pyrenees and Spain, and on trade routes between Toulouse and Aragon.
The dynasty of the Counts of Comminges dominated the region for several centuries.
Among the most important were Bernard IV of Comminges (12th century), who participated in feudal struggles in the South and strengthened comital authority, and Bernard V of Comminges, who was involved in rivalries between major southern families.
The counts constantly had to negotiate with powerful neighbors: the Counts of Toulouse, the Kings of Aragon, and the Gascon lords.
Changes in Comminges following the Albigensian Crusade in the 13th century.
The territory was less affected than central Languedoc but remained involved. The counts tried to balance their relations between the crusaders from the north and the great Occitan families.
After the crusade, French royal power gradually expanded in the south, and the autonomy of the smaller counties diminished.
Medieval Comminges society was typically feudal, with the nobility, who owned castles in the Pyrenean valleys, remaining loyal to the count. The clergy, including the bishopric of Saint-Bertrand-de-Comminges, played a central role. Religious influence grew, and pilgrimages multiplied. Peasants developed agriculture, particularly in the mountains, livestock farming, and forestry.
Villages were often organized around a church, a castle, or a feudal motte.
Several factors weakened the county:
- demographic crises (Black Death)
- economic difficulties
- gradual extinction of the dynasty.
In 1454, Comminges was attached to the French crown under the reign of Charles VII.
It then became a province integrated into the kingdom, while retaining a strong regional identity.
In our destination, there are 3 former comital cities whose remains from this era can be seen in their town centers: Saint-Marcet, Aurignac, and L’Isle-en-Dodon. Each of these towns had its castle; remains are still standing in Aurignac and Saint-Marcet, while in L’Isle-en-Dodon, only a castle wall is visible on Rue Maubec.
The Great Medieval Castles of Comminges
Saint-Marcet Castle
The Château de Saint-Marcet is one of the important castle sites in Comminges.
Its function was to control an agricultural territory and local routes.
The current owner of the castle has spent a large part of his life renovating the site, which is private. In its current state, although partly in ruins, one can still understand the organization of a medieval castle in the region.
Aurignac Castle
Surrounded by walls 1.5m to 2m thick, it forms a rectangular enclosure when the northeast part, where the Count’s lodging was located, is added. The ramparts are reinforced by four solid cylindrical corner towers, formerly crowned with battlements. The keep was an uncovered watchtower; it is now the only building from that era still standing. It is accessed by a staircase and the original door. This enormous, slightly truncated conical structure rises 18 m high with an external diameter of 9.25 m at the base and 8.25 m at the top. It comprises 3 superimposed rooms. One ascends via a narrow spiral staircase built within the thickness of the walls, between two concentric towers.
Montespan Castle
The ruins show its medieval role, both as a strategic surveillance post and protection for routes between Saint-Gaudens and the Pyrenean valleys.
Built around the 13th century, it belonged to a powerful local family, the Montespans, whose Marquise de Montespan left her mark on history.
Today, the site offers a panorama of Comminges.
Other medieval remains in Comminges: religious heritage
Many small villages have their churches dating from the Middle Ages, such as Aurignac, L’Isle-en-Dodon, Boulogne-sur-Gesse, Saint-Marcet, and many others… We must mention the majestic Collegiate Church of Saint-Pierre in Saint-Gaudens, the Sainte-Marie Cathedral in Saint-Bertrand-de-Comminges, and the Saint-Just Basilica in Valcabrère.
Former convents, monasteries, and abbeys like the Bonnefont Abbey, and in Alan, the former bishops’ palace… all this heritage tells the story of Comminges during this period.
