This map of the Ain region is a working document on which the Commission de Topographie des Gaules (CTG) noted in pencil the information sent by CTG correspondents to help it produce its maps and plans. This large collection, Atlas paléoethnologique par départements, contains 1,141 pages of forms and maps.

[The illustrations on this page allow you to see each of the stages in the production of the archaeological map of Gaul, using the example of the site of Cormoz (or Château-Gaillard) in the Ain region.]
