This may explain why, around the year 531, bishop Medardus moved his seat from Vermand in the Vermandois to Noyon. (Another option was to move his seat to Saint-Quentin but the wine produced in Noyon was thought to be much better than that produced in Saint-Quentin.[5] Other explanations are that Medardus was born near the town, at Salency, or that the place is nearer to Soissons, which was one of the royal capitals of the Merovingians.) The bishop of Noyon was also bishop of Tournai from the seventh century until Tournai was raised to a separate diocese 1146.[6]
