 The town has very little relief with the average altitude being 25 metres – ranging from the lowest point of 12 metres at "Lake Frace", to the highest point of 38 metres at the small hill, between the site of "Pannonière" and the low hills in the commune of "Saint-Christophe", north of "Aigrefeuille d'Aunis".All of the commune is located in a flat area, with wide horizons, yielding a landscape based on the open field system characteristic of farming in Europe.
