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 Jeantes is a historic monument located in the Aisne department, in the Hauts-de-France region. It dates from the 16th century and has a facade flanked by two square brick towers. The interior of the church is decorated with murals and frescoes created by the Dutch painter Charles Eyck in 1962, as well as remarkable stained glass windows. The paintings represent scenes from the gospel and landscapes of Thiérache, in a style close to expressionism and the work of Chagall, Picasso or Modigliani. The stained glass windows illustrate the life of Monique Carlin, founder of a religious congregation, and the four elements. The church has been listed as a historic monument since 1987.
