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.

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.

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

The Église St Léger in Cléty is a Catholic church located in the heart of the village, surrounded by a cemetery1. The church is of simple design, with a single nave and a semicircular apse2. It dates from the 16th or early 17th century and has a tower built in 1662 or 16651. The church has a benitier with a basin in brown marble in Louis XV style, a 0.68 m wooden statue from the 16th century of Sainte Anne, the Virgin and the Child Jesus, and a staircase to the top of the tower where a bell can be seen - there used to be two - with a diameter of 1.10 m, cast by Pierre Voulemin in 1678 and donated by Mary, wife of Adrien de Mames (Mametz), lord of Cléty
