Argentomagus, Gallic oppidum - Marcel Saint, Indre :

the town of Argenton was where (are) now certain large farmhouses of wines called the castle(lePalais), holy walls (Mersans) and Virou... One still sees there the ruins of several beautiful and sumptuous artificial fountains whose channels are made of marble [... ] and whose drying ovens are made of alabaster... All these antiquities reveal enough which was the size and magnificence of the aforementioned old city.
