Tournai, known as Tornacum, was a place of minor importance in Roman times, a stopping place where the Roman road from Cologne on the Rhine to Boulogne on the coast crossed the river Scheldt. It was fortified under Emperor Maximiam in the 3rd century AD, when the Roman limes was withdrawn to the string of outposts along the road. It came into the possession of the Salian Franks in 432. Under King Childeric I, whose tomb was discovered there in 1653, Tournai was the capital of the Frankish Empire. In 486, Clovis moved the center of power to Paris. In turn, a native son of Tournai, Eleutherius, became bishop of the newly created bishopric of Tournai, extending over most of the area west of the Scheldt. In 862, Charles the Bald, first king of Western Francia and still to become Holy Roman Emperor, would make Tournai the seat of the County of Flanders.
