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 neo-Gothic church was built before 1597 and replaced another building from the 11th century, which stood near the current chapel of Notre-Dame des Affligés. It was partially rebuilt in 1855. The tower dates from 1683. The originality of this construction lies in the fact that the bell tower is not above the entrance door, but above the choir. The door is simply formed by a pointed arch decorated with a pentacle. The first two bays of the nave are built of red brick and the last two in chalk. The four bays of the nave also have a pointed arch. The bell tower is formed by a gable wall that projects above the nave. The buttresses on this side are placed in line with the wall, creating a flat surface. The buttresses of the bell tower on the choir side are well placed on the corners
