Its limestone plateau reaches 88 metres, near Château Jeandeman (see link below) and the lieux-dits of Escotebise and Les Tonnelles. Beneath the limestone lies Molasse du Fronsadais, here slightly clayey. There is evidence of Gallo-Roman settlements here, not all of which have been excavated. Relics have aldo been found from the Merovingian dynasty under the ruling family of the Franks from the mid-5th century until 751).
Vineyards: Around 200ha of vines (the commune only has 275ha of land in total). The highest point is close to 80 metres, hence the presence of several ageing windmills.
