The entry for Château-Gaillard, on pages 272-273 of the Dictionnaire archéologique de la Gaule, is based on the information provided to the Commission de Topographie des Gaules on the form sent by Guigue, one of its correspondents, in 1864. In it, remains are represented by symbols and a description adds context.

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