In 1639, the plague wreaked havoc in the region. In Chapelle-des-Bois, it killed roughly fifteen of the 150 village inhabitants. Fearing that they might catch the illness, survivors did not want to bury the dead in the cemetery. Their decision to bury the plague-ridden corpses in the peat bog is no accident. Considered worthless land, and rarely used for agricultural purposes, the peat bog seemed the ideal place to bury victims of the plague without contaminating the land.
