Ptolemy lists the Santonon Akron and a homonymous port (Santonon Limen) on a stretch of the Atlantic coast of modern France between the mouths of the ancient Garumna (Garonne) and the ancient Ligeiros (Loire) where there has been significant landscape change since antiquity. In his Periplus, Marcianus puts it between the mouth of the Garumna and the mouth of the Kanentellos (modern Charente). It may be identifiable with the modern Pointe d'Arvert/Pointe Espagnole, which lies just north of the mouth of the Garonne, or (if Marcianus is discounted) with the Pointe des Baleines, which is the northwest cape of the Île de Ré, which lies offshore from modern La Rochelle.
