Aguiéne can be viewed on this map.
It comprises the following zones:
- From a historical point of view, the traditional provinces of Poitou, Saintonge, Aunis and Angoumois.
- From an administrative point of view: the official region of Poitou-Charentes and the department of Vendée (adding some strips of the nearby departments of Loire-Atlantique, Maine-et-Loire, Indre, Dordogne and Gironde, but removing a western strip of Poitou-Charente where Occitan is spoken).
