 A witness to this evolution was the Saint-Étienne church, which was built in the middle of the 12th century in the heart of the original village but rebuilt several times in the Middle Ages, particularly in 1360 and especially the 15th century, when it was restored and strengthened after the Hundred Years' War.In the Middle Ages, "Aigrefeuille d'Aunis" was at the centre of a large clearing in the forest.The ancient "Forest of Argenson", which separated the old provinces of "Aunis" and "Poitou", was gradually reduced and extensive clearings were carried out mainly for vineyards which, at "Aigrefeuille", were at the southern limit of the plain of "Aunis".
