Angliers is located some 15 km north-east of La Rochelle and 15 km south by south-east of Marans. National highway N11 (E601) passes through the north of the commune and there is an exit at the north-eastern tip of the commune to the D109 road which runs south through the commune to Vérines. Access to the village is by a country road off the D109. There is also the D203E1 road running from the hamlet of Saint-Gilles west to Loiré. Apart from the village, there are also the hamlets of Le Grand Peu, Saint-Gilles, and Les Loges. The commune is entirely farmland.[3]
Angliers commune is divided into two clearly distinct parts:
To the west, the commune is a part of the plain of Aunis and is characterized by rolling limestone hills.
To the east is a marsh which is part of the Marais Poitevin.
The swamp is drained by the waters of the Curé river which is a small coastal river and serves as the eastern boundary of the commune. This river has its source in the commune of Saint-Georges-du-Bois and becomes a Canal before emptying into the Bay of Aiguillon. It is called the Canal du Curé at Angliers. Formerly, the eastern part of Angliers was always flooded along the road north of the commune that joins the village of Le Grand Peu to Nuaillé-d'Aunis. Angliers is at the southern limit of the Marais Poitevin.
The history of Angliers before Gallo-Roman times has been lost, as with many neighbouring communes. However, a few important remains have been found. Sarcophagi found in the 19th century at Gillebergère are not necessarily from those remote times.
Ancient relics are rare but the door of the church dates from 1100/1130. It once came under the Abbey of Nieul-sur-l'Autise. This church has undergone many changes throughout its history mainly because of the Hundred Years War and the Wars of Religion. The fighting that took place around the castles of Benon, Nuaillé-d'Aunis, and Surgères suggest many passages by the Port Bertrand through the east of Angliers to the town of La Rochelle.
