[1] The Gothic cathedral dates from the 13th and 14th century and occupies the site of three earlier churches.

The west front, which is disfigured by the buttresses projecting beyond it, has two stately spires of open work 230 ft. high.

In the choir are four bas-reliefs of great beauty representing scenes in the life of the Virgin Mary; and the altar is adorned with another depicting the removal of the relics of Saints Gervais and Protais.

Sunday afternoon recitals are held during July and August.

In 2015, during restoration work on the North Tower, three new bells were installed.
