At the edge of the forest, between Dommartin and Vuillecin, stands a modest chapel. It has a strange name: Niai Nion or according to the map of the region: Gnégnon. From this place the view extends over the Chaux d'Arlier, Pontarlier and the heights of Larmont. Everything is calm, conducive to meditation, but in the distant past this place was the scene of painful events.
Indeed, in 1636, the black plague devastated the region and multiplied the land in the cemeteries known as the Bossus. For fear of contagion, the sick of Dommartin, Houtaud and probably Vuillecin, were led, a few hundred meters from the village, in a narrow valley sheltered by the forest, near a spring. A person from Bannans, Jeanne Laignier, volunteered to be their nurse. Alas! in her turn she was affected by the terrible disease and repeated sadly in dialect: "lai soigni lès autres et niai nion pou m'soigni!" that is to say: "I treated others and I have no one to treat me. Niai nion, I have no one, became the name of the chapel. Jeanne Laignier joined the 120 plague victims who were buried in the cemetery. A stone slab indicates the place of burial. The inscription on it is no longer legible, but at the beginning of the century, it still reads: Jeanne Laignier, died on September 8th 1636. Surprising detail: for more than three centuries, the grass has never covered this slab and the inhabitants of Dommartin-Houtaud consider Jeanne Laignier as a saint. Following these events, the inhabitants of the parish decided to build a chapel dedicated to the Holy Trinity and to place the statues of St. Roch and St. Sebastian, which are invoked against contagious diseases, including the plague. The chapel and the cemetery are surrounded by a dry stone wall and protected by large trees.
From time immemorial, the parishioners of Dommartin go in procession to Niai nion on Trinity Sunday. It is an opportunity for them to meditate on the heroism of Jeanne Laignier who testified by her sacrifice "that there is no greater love than to give one's life for those one loves".
