Built on the remains of a Romanesque cathedral from the 11th century, the Gothic cathedral of Saint-Paul-Aurélien, a minor basilica known as the Annunciation, has a remarkable nave from the 12th century in Caen limestone, a complex almost unique in Brittany, and a choir in granite from the 15th century.

Raising its spire almost 80 metres high, the Kreisker chapel (14th/15th century) is the tallest bell tower in Brittany and the most beautiful example of openwork bell towers. Its dozens of openings do not provide any wind protection. Its reconstruction after the fire of 1375 is attributed to an English architect. The building was, until the 16th century, a municipal chapel, housing the deliberations of the city council and then, until the Revolution, which brought down the bells, the chapel of both the Grand Seminary and the Collège de Léon. In 1806, the Kreisker was attached again to the Coliège de Léon, which in the 20th century became the Institution Notre-Dame du Kreisker.
