The belfry of Aire-sur-la-Lys (in Dutch: Ariën-aan-de-Leie) is a historic, baroque belfry in the French department of Pas-de-Calais that has been on the UNESCO World Heritage list since 2005. The striking tower is attached to the town hall and dominates the skyline of the historic town.

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.

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.

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.

This Spanish mill was built around 1635, on the banks of the Lacquette River. It produced flour until 1938, then milling for livestock. It was bought in 1974 to be transformed into a home. It is built with brick and stone (white limestone). All that remains of the original building is the north gable (17th century), and also a porch. The water wheel is still in place but it no longer turns. The dam forms a pretty waterfall. A turret was added on the river side. It is a very beautiful private home with a beautiful garden in which you can see a stone fountain.

The Beffroi d'Aire-sur-la-Lys is a monument that is part of the heritage of Aire-sur-la-Lys. It was first built in 1355 and rebuilt between 1716 and 1724 by the architect Hérogue. It has been listed as a historic monument since 1947 together with the adjacent town hall1. The beffroi is 45 meters high and rests on four large pillars of brick and stone, two meters thick, which demarcate an interior space of six meters wide. It is of Baroque style and is part of the list of 23 belfries inscribed on the UNESCO World Heritage List in 2005 as part of the list of "Belfries of Belgium and France".
