Cazères-sur-Garonne is located between Toulouse and the Pyrenees, at the gateway to the Petites Pyrénées, where the Comminges and Plantaurel regions meet. Originally, it was a small Gallo-Roman town built on the Montjoie promontory and bordered by the Hourride and Garonne rivers. Cazères appears in history in medieval times, when the first church was built there.
Successively under the control of the House of Comminges and then the County of Toulouse, in the 14th century Cazères came under the control of the House of Foix, then ruled by Gaston Phoebus. During this period, the town suffered from the troubles and wars that ravaged the region. The first fortified village of Cazères was built under the protection of the first castle. It was small, the bilo barrado or little Barrade. A second, much larger settlement developed later to the west. It has a geometric street grid characteristic of the 13th century. A
In the 18th century, Cazères was an important port. Boat building began around 1750. The birth of intense traffic between our region and Toulouse can be explained by Toulouse’s need for Belbèze stone, firewood and plaster extracted from the Roquefort quarries.
