The Church of Saint-Jacques, a stunning Gothic structure in Montauban, traces its origins to the early 12th century. The original church was replaced in the 13th century by the current building, with construction starting in 1241. Funded by wealthy citizens of the town, the church's construction spanned several centuries, culminating in the 15th century when the structure was expanded, and the entrance tower was added. Beyond its religious role, the church also served as a center for civic governance, hosting the election of city consuls.
During the Wars of Religion, Montauban became a Protestant stronghold. The church was repurposed for military uses: its nave served as a gunpowder factory, the choir became a fortified position, and the tower functioned as a watchtower during the failed siege by a royal army in 1621. The structure sustained damage from cannon fire during the conflict. Eight years later, the royal army entered the city, and Cardinal Richelieu held a Te Deum in the church to celebrate the victory. He ordered its reconstruction in the original Gothic style. Between 1629 and 1739, before the completion of the Notre-Dame Cathedral, the Saint-Jacques Church temporarily served as the cathedral of the Montauban diocese.
Over the centuries, additional modifications were made. In the 18th century, side portals were added, and the 19th century saw the installation of a Neo-Romanesque facade. Since 1918, the Church of Saint-Jacques has been recognized as a protected historic monument.
Built from the region’s characteristic pink brick, the church reflects the architectural style typical of Toulouse. Its octagonal tower is a defining feature of the area. The facade is adorned with a large, colorful mosaic, adding vibrancy to its Gothic design. Inside, the nave consists of five bays crowned with ribbed vaults, while the choir is elaborately decorated with murals and terminates in a seven-sided apse. Together, these elements highlight the church's rich history and artistic significance, making it a landmark of Montauban’s cultural heritage.
The Château de Foix dominates the town of Foix. An important tourist site, it is known as a centre of the Cathars. Built on an older 7th-century fortification, the castle is known from 987. In 1002, it was mentioned in the will of Roger I, Count of Carcassonne, who bequeathed the fortress to his youngest child, Bernard. In effect, the family ruling over the region were installed here which allowed them to control access to the upper Ariège valley and to keep surveillance from this strategic point over the lower land, protected behind impregnable walls.
In 1034, the castle became capital of the County of Foix and played a decisive role in medieval military history. During the two following centuries, the castle was home to Counts with shining personalities who became the soul of the Occitan resistance during the crusade against the Albigensians.
