This vast church is both Romanesque and Gothic. The sumptuous 14C portico on the left was built when Gaillard de la Mothe, the nephew of Pope Clement V, was Dean of the canons. Its tympanum is sculpted with a fine Last Judgement. Only the bases of the statues of the apostles which decorated the niches now remain. The 12C murals representing the Virgin Mary and the legend of St Catherine can be found on the right-hand wall of the nave.

In addition to lessons and hiring out sail-boats, the Pierre Mallet centre offers a number of sea activities such as sea kayaking, rowing and diving.

This captivating square is lined with attractive houses set on Gothic and Renaissance covered arcades. The workmanship of the 15 and 16C houses with arched bays or transom windows is first-rate.

The former market square is representative of Louis XV urban planning with its well-ordered dwellings, some of which are characterised by a ground floor of arcade, impost windows and decorated with masks. The balustrade running across the façades accentuates the unity of the buildings.
