Argentomagus
Saint-Marcel, France
The Roman city of Argentomagus was located in the Mersans plateau of central France, at the strategic point on the north bank of the river Creuse, where a Roman bridge once traversed. It was located at the crossing of two roads—Cenabum (Orléans) to Augustoritum (Limoges), and Limonum (Poitiers) to Avaricum (Bourges). The Latin name of the city meant "Silver Market." The modern town of Argenton takes its name from the ancient site of Argentomagus.
