Abbeville is located on the Somme River, from its modern mouth in the English Channel. The majority of the town is located on the east bank of the Somme, as well as on an island. It is located at the start of the Abbeville Canal, and is northwest of Amiens. In the medieval period, it was the lowest crossing point on the Somme. Edward III's army crossed nearby shortly before the Battle of Crécy in 1346.
