Senlis was known in early Roman imperial times as Augustomagus and later as Civitas Silvanectium (City of the Silvanectes). During the 3rd century, a seven-meter high defensive wall, about half of which is still extant, was erected around the settlement in response to the first incursions by the Franks. The town's amphitheatre (arena) seated as many as 10,000 people and was used for public meetings, theatre, gladiatorial combats and animal hunts. http://en.wikipedia.org/wiki/Senlis,_Oise In the 3rd century, Saint-Rieul (a companion to Saint Denis) évangélised Senlis. The election of Hugues Capet (987AD), the premier ruler of the Capétiens, favored the religious and economic life of the city. Many people from all over come to admire the cathedral's western portal, which features the premier stone representation of the Virgin's Ascension to Heaven. -- Views of Cathedal portals And, there is even a Sainte Jeane d'Arc connection (1429).
The former Catholic Diocese of Senlis existed from the sixth century, at least, to the French Revolution. The See was at Senlis. Suppressed by the Concordat of 1801, its authority passed to the Diocese of Beauvais. http://catho60.cef.fr/histoire/temoins/temoins.htm (française -- grandes figures chrétiennes et Saint(e)s de l'Oise et France)
