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 Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
