Fouille with a surface area of 6 600 m² over a period of 11 months, which made it possible to measure the development of an urban district over two millennies.The main discovery corresponds to an arc, made up of masonry sites over a 55 m development, retaining 6 m of elevation, with the rear opening of arcades, discharge arcs or underground passages, and, forward, foothills and two powerful masonry frames framing monumental stairs serving the shelves. This elliptical plan belongs to an amphitheatre of 90 x 110 m, the presence of which in Cahors could not be assumed. The site’s activities (lime ovens, forge residues) date back to the construction of our 80s. Other major elements of the Roman city’s urban organisation, the Cardo maximus (early 1st century) has also been highlighted, as well as a large public monument of 120 m and over 40 m long with a colonnade and outsides, probably corresponding to the forum built in the second half of the 1st century. During the late antiquity and the high Age, the two public monuments were dismantled and a temporary installation (habitat, animal park, etc.) came from the middle of the centuries. Other constructions relate to brick-built buildings such as latrines and house cellars. There are also several battery furnaces which produced luxury ceramics at the end of the nineteenth century. Modern times saw the arrival of the Jews (17th century), and contemporary times saw the creation of promenades with a music kiosk (1812), a fountain (1870) and successive monuments dedicated to Fénelon (1820) and then Gambetta (1884).
