Although Tournai is in the Flemish cultural area (of the Scheldt), it also possesses some treasures of the Mosan style. Indeed, the two most beautiful shrines of the Cathedral, commissioned by the Bishop of Tournai, were made in the region of Liège by the artist Nicholas of Verdun: the shrines of "Saint-Eleutherius" and of "Our Lady of Flanders" (13th century). Those shrines testify to the opulence of the towns of Tournai and Liège during the Middle-Ages. The shrine of "Our Lady of Flanders" has been called one of the seven wonders of Belgium.
