 The great builders were Bishop Bartholomeus de Roux and Bishop Raimond de Cornil.In 1285 Bishop Raimond persuaded the Chapter to join with him in a commitment to donate half of the first year of income of every newly granted benefice in the diocese to the building fund.When, in the Middle Ages, the bishops officiated in this church they had the privilege, as barons and counts of Cahors, of depositing their sword and armour on the altar.
