Question: Who is the cathedral in France that was the seat of the bishop of Apt until the French Revolution dedicated to ?

text: List of cathedrals in France
Roman Catholic cathedrals

This is a list of cathedrals in France and in the French overseas departments, territories and collectivities, including both actual and former diocesan cathedrals (seats of bishops). Almost all cathedrals in France are Roman Catholic, but any non-Roman Catholic cathedrals are listed here as well. The list is intended to be complete as far as current cathedrals and co-cathedrals are concerned. It is not yet an exhaustive list of former cathedrals, although it includes most of them. A number of large churches in France are known as cathedral as a mark of distinction or historical importance but have never been the seats of bishops. These are not included here.
