One of the oldest churches in the French city of Carcassonne, which dates back to the twelfth century. It is a very beautiful church designed in the Gothic architectural style, characterized by distinctive structural forms and new expressionism in terms of prominent arches, fan arches, flying buttresses, stained glass windows, sculptures distributed throughout the place, and more. What distinguishes the architecture of the church is the presence of a vibrant rose window adorning its facade.
