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.

From 1859 onwards, the permanent church was built and in 1860 the tower was built. In 1865 the choir was restored and in 1866 a new sacristy was built. This church was consecrated in 1872. The stained glass windows of this church show the coats of arms of the bishops of the former diocese of Thérouanne. They were installed in 1901-1902.

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 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

Kelmes in West Flanders. The Saint-Pierre church: 13th century The monument aux morts. Discover in this church a monumental ceramic tile of 10/10 representing Saint Peter, made in the 1950s by Father Dom Bouton. We see the monk's trademark: a drawing with a black outline that he fills with flat surfaces of bright colours. The liturgical arrangement, i.e. the altar, the communion rail, the tabernacle and the side altars are made of earthenware and come from the workshops of Wisques. It is difficult to determine, in the absence of exact sources, who is the author of these works, knowing that the monks of the artist collaborate.
