town, Somme departement, Picardy region, northern France, near the mouth of the canalized Somme, northwest of Amiens. Stone Age artifacts unearthed by Boucher de Crevecoeur de Perthes in 1844 attesting to early occupation of the site are displayed at the Musee Boucher-de-Perthes. The town originated as Abbatis Villa, a 9th-century dependency of the abbots of Saint-Riquier, and was chartered in 1184. Under the English (1272-1435), it was capital of Ponthieu. Louis XII's marriage (1514) to Mary, sister of Henry VIII of England, took place there. The Gothic church of Saint-Vulfran (15th-17th centuries) and the town hall with its 13th-century tower survived air bombardment during World War II, which destroyed the greater part of the town.
