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.

Leaving the village of Dohem via Rue du Paradis, the Via Francigena takes you along a pleasant tree-lined path.

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.

Thérouanne is stop 77 of Sigeric on his return journey from Canterbury to Rome. The town is also located on the historic road between Boulogne and Arras (Chaussée Brunehaut). In the 16th century, this fortified town was a French enclave within the German Empire, but was razed to the ground by Charles V in 1553. On the hill to the north of the town lie the remains of one of the first cathedrals built in the Gothic style in France. The famous Grand dieu de Thérouanne, which once adorned one of the portals, is now in the cathedral of St-Omer.

The Rebecques ponds are fishing ponds, but they are no less beautiful to admire. They are open all year round, from sunrise to sunset.
