The Courtgain district and its Calvary This is the district that used to be inhabited by sailors in the 18th and 19th centuries. They went fishing aboard their grasshoppers, these flat-bottomed boats with a large square sail. They mainly fished for gray shrimp, locally called "grasshoppers" because they swim, walk and jump in the sand and water. Despite difficult and dangerous working conditions, sailors earned little money. It is from these short profits that the district takes its name. Spared by the war, the typically Picardy buildings have retained their old-world charm thanks to the inhabitants who strive to perpetuate the traditional aesthetics of fishermen's houses: flowery and colorful facades, as in the days when surplus paint intended for boats was used to decorate the house. The Courtgain district is richly decorated, notably with fishing nets and gladioli, and is the epicentre of the Fête de la Mer, held every August to honour the missing sailors. Walk through these alleys and go to the Calvary of the Sailors. It offers a clear view of the Bay of Somme. This is where women went to see the return of their husbands who had gone to sea.

The church is built of natural stone with a characteristic pattern. It consists of two naves, separated by high arches. The baptismal chapel is still part of the original church. A church was first mentioned in the 12th century, but the current church dates back to the 13th century. The church was repeatedly destroyed during the Hundred Years' War and was set on fire in 1475, when the city defended itself against the English and Burgundian rulers. The church was rebuilt at the end of the 15th century and reconsecrated in 1500, but construction activities lasted until 1559. During the French Revolution, the furniture was sold, shrines and paintings were burned and bells were melted down. In 1845, a rectangular brick building was built next to the tower. Next to the church is the heavy tower, equipped with buttresses. In 1786, it was crowned with a tent roof.
