In 1064, two years before the Battle of Hastings, Harold Godwinson, then Earl of Wessex, was shipwrecked on the shores of Ponthieu and captured by Guy I, Count of Ponthieu(d.1100) who took him to his castle of Beaurain, situated 24 1/2 km up the River Canche from the English Channel coast, (now Le Touquet), as the Bayeux Tapestry relates: HIC APPREHENDIT WIDO HAROLDUM ET DUXIT EUM AD BELREM ET IBI EUM TENUIT ("Here Guy seized Harold and led him to Beaurain and held him there"). Duke William of Normandy demanded the release of the earl, and Count Guy delivered Harold Godwinson up after being paid a ransom for him.
