Thérouanne was Sigeric's 77th stop on his return from Canturbey's pilgrimage to Rome. In the 19th century, this fortified town was a French enclave within the German Empire, but was razed by Charles V in 1553. On the hill north of the town are the remains of one of the first cathedrals built in the Gothic style in France. The famous Great God of Thérouanne, which adorned one of the portals, is now housed in Saint-Omer Cathedral.

The small village of Delettes includes the hamlets of Upen d'Amont, Upen d'Aval, and Westrehem. Crossed by the Lys River, it boasts a pretty sluice mill built on the banks of the river.

At the entrance to Thérouanne is the site where a magnificent cathedral stood in the Middle Ages... Today, there is practically nothing left on the surface, but a walk in this park after visiting the Maison de l'archéologie allows you to better immerse yourself in the history of Thérouanne and imagine the splendor of the city in medieval times.
