Abbeville is a commune in the Somme department and in Hauts-de-France region in northern France. It is the chef-lieu of one of the arrondissements of Somme. Located on the river Somme, it was the capital of Ponthieu. Abbeville is the seat of the Chambre de commerce et d’industrie d’Abbeville – Picardie maritime. It manages ports, the aerodrome and industrial areas of the arrondissement of Abbeville. Abbeville manufactured textiles, and in particular, linens and tablecloths when the Van Robais family created la Manufacture Royale des Rames in 1665; however after the Edict of Nantes was revoked and the subsequent migration of Protestants away from the area, the cloth business succumbed. Also affecting the economy of the town was the closure of the river port on the Somme River due to excessive silt. It also has cordage factories, carpet factories, and spinning mills. Finally, it also fabricates locks, has breweries, and produces food and, until 2007, sugar. The subsoil contains many vestiges of the Pleistocene. This discovery was a founding element of prehistory as a science. The name Abbeville has been adopted to name a category of paleolithic stone tools. These stone tools are also known as handaxes. Various handaxes were found near Abbeville by Jacques Boucher de Perthes starting in 1838 and he was the first to describe the stones in detail, pointing out in the first publication of its kind, in 1846, that the stones were chipped deliberately by early man, so as to form a tool. These stone tools which are some of the earliest found in Europe, were chipped on both sides so as to form a sharp edge, were known as Abbevillian handaxes or bifaces, but recently the term ‘Abbevillian’ is becoming obsolete as the earlier form of stone tool, not found in Europe, is known as the Oldowan chopper. Some of these artifacts are displayed at the Musee Boucher-de-Perthes. A more refined and later version of handaxe production was found in the Abbeville/Somme River district. The more refined handaxe became known as the Acheulean industry, named after Saint-Acheul, today a suburb of Amiens. It retained some importance into the Bronze Age.
