Born in the 1st century, Cahors (Divona Cadurcorum) was linked to the Gallic worship of the Divona spring (Fontaine des Chartreux). Today, Boulevard Gambetta follows the route of the first ramparts erected by Bishop Saint Géry in 650. Under the impetus of Bartholomew, Bishop of Cahors, the Quercy region prospered in the 13th century. Pope John XXII, a native of the city, gave the goods of the Templars to the Carthusians and founded a university. The arrival of Lombard bankers at that time made Cahors one of the most important financial centers in Europe.
