Roman Catholic Diocese of Montefiascone

The diocese of Montefiascone (Latin Name: Faliscodunensis o Montis Falisci) was a Catholic ecclesiastical territory in Italy.

[1] In 1986 was incorporated into the diocese of Viterbo, Acquapendente, Bagnoregio, Montefiascone, Tuscania e San Martino al Monte Cimino.

[5] Pope Urban V had stayed at Montefiascone during his journey from Avignon to Rome, and was greatly impressed by the loyalty and affection of the inhabitants toward himself and his predecessors.

[6] The diocese of Montefiascone was erected by Pope Urban V by the papal bull, Cum Illius of 31 August 1369.

He appointed the church of S. Margarita to serve as its cathedral, and he installed in it a Chapter composed of two dignities (the Dean and the Sacristan) and eight Canons with prebends.

In 1483, Bishop Domenico della Rovere laid the cornerstone for the new cathedral of S. Margarita in Montefiascone, and in his Last Will and Testament in 1501 he left money to continue the work, which had barely reached the level of the main floor of the church at the time of his death.
