Monon de Nassogne was a Scottish hermit and martyr who lived during the seventh century. After leaving his native Scotland, he traveled to the European continent to live a solitary life in the Ardennes forest. Around 645 AD, he was killed by robbers in his cell in Nassogne, located in present-day Belgium. Following his death, his remains were placed in an oratory, which eventually became a site for pilgrims seeking spiritual aid.
