The former French Catholic diocese of Senlis existed from the sixth century, at least, to the French Revolution. Its see was at Senlis, in the modern department of Oise, in northern France.
It was suppressed by the Concordat of 1801, its territory passing to the diocese of Beauvais.[1]
Rieul of Senlis is considered the first bishop, probably around the early fourth century.[2] The first cathedral was built in the late 4th or early 5th century, within the perimeter of the city walls.[3] According to Butler, Léthard was chaplain of the Frankish princess Bertha, and resigned the see in order to accompany her to Britain when she married Æthelberht of Kent.[4]
Gregory of Tours says that when king Chilperic I was assassinated, he was deserted by his people who had no love for him, however, when Bishop Maculphe heard of the king's death, he set out to take the king's body and had it buried in the church of Saint Vincent in Paris.[5] Ursion was Chancellor of France in 1090, as was his successor, Hubert, in 1091.
Construction of the Cathédrale Notre-Dame de Senlis was started around 1151 on the site of older sanctuaries, under Bishop Pierre.[6]
