Basilica of Saint-Sernin, Toulouse

The Basilica of Saint-Sernin (Occitan: Basilica de Sant Sarnin) stands in Toulouse, France, as the former abbey church of the Abbey of Saint-Sernin (or St Saturnin). All other abbey buildings have been lost. This church occupies the site of a 4th-century basilica that once held the remains of Saint Saturnin (also called Sernin), the first bishop of Toulouse, who died around 250. The building is famous for the high quality and large amount of its Romanesque sculpture. In 1998, it became a UNESCO World Heritage Site as part of the Routes of Santiago de Compostela in France.

The abbey itself was an old foundation, with a 4th-century basilica built under Bishop St Sylvius of Toulouse. Its importance grew greatly after Charlemagne (ruled as King of the Franks 768–814, and as Emperor from 800–814) gave it many relics, making it a key stop for pilgrims traveling to Santiago de Compostela and a pilgrimage destination on its own. The current building’s size and its ambulatory likely reflect the need to handle growing numbers of pilgrims.

Pinpointing when Saint-Sernin was built and its sculpture finished is tricky. As early as the 1010s, Bishop Pierre Roger set aside some of the church’s offerings for a future rebuilding of the Carolingian church. By the 1070s, and no later than 1080, the canons had adopted the Rule of St Augustine and placed themselves directly under the Holy See. Only two firm dates relate to the church itself, and even these come with problems. On May 24, 1096, Pope Urban II dedicated the altar of the still largely unfinished building. It is certain that construction had begun at least several years before that date. The second firm date is July 3, 1118, the death of St Raymond Gayrard, a canon and provost. A 15th-century biography claims he took charge of the building after part was done and had “brought the walls all the way around up to the completion of the windows” by his death. However, that biography was written about 300 years later, and since at least three different Raymonds were involved in the building, the writer may have mixed up their stories.

Whenever it started, construction did not run continuously. Physical evidence shows several interruptions. The literary clues suggest building moved from east to west.
