The faithful trust in the help of the Mother of God – who in France is always venerated under the title “Notre-Dame” (which corresponds to the German name “Our Lady”) – was expressed by the French nun, mystic and Doctor of the Church, Saint Thérèse of Lisieux (religious name Thérèse of the Child Jesus and the Holy Face, 1873 to 1897) as follows: “In trials or difficulties I turn to Mother Mary, whose gaze alone is enough to dispel all fear.”

The fortified church of Plomion is one of the most remarkable in Thiérache. Completely renovated and freely accessible upstairs, since June 25, 2022, it was built in bricks and stands on the foundations of an old church, where a permanent garrison was stationed. This church is the "finished" type of fortress church which includes all the elements of fortification: tower, keep, turrets, watchtowers and a set of more than 60 loopholes including 42 on the keep! Numerous geometric patterns in vitrified bricks such as hearts and diamonds adorn the building.

A first church was probably built there as early as the 12th century. Nothing can be seen of it anymore, although the lower parts of the watchtowers at the corners of the east facade may still belong to the original building.

The history of the village of Saint-Algis, whose church of the same name is located in a very picturesque location overlooking the Oise valley, began in the 7th century, when six Irish nobles and devout Christians arrived in Thiérache to evangelize the country. Among them was Aldalgis, who settled here on the banks of the Oise and died there on June 6, 670, having accomplished his work.
