Aaron of Aleth was a 6th-century monk, hermit, and abbot who is believed to have traveled from Wales to Armorican Domnonia. After living as a solitary figure near Lamballe and Pleumeur-Gautier, he established himself on the island of Cézembre, located near Aleth. During his time on the island, he attracted numerous visitors, including Malo, who eventually succeeded him as the spiritual leader of the region. He is recognized as a saint within the Catholic tradition.
Life and ministry
Originally from Wales, Aaron spent time living alone before settling on an island near the settlement of Aleth. His reputation as a hermit drew many followers to his location. Following his leadership, Malo became the first Bishop of Aleth. This transition helped establish the religious foundation for the district that later became known as Saint-Malo.
Veneration and legacy
He is commemorated as a saint, with his feast day observed on June 21 in Saint-Malo or June 22 in other locations. His influence remains visible in Brittany, as the town of Saint-Aaron in Lamballe is named in his honor. He is also recorded in the historical text Les Vies des Saints de Bretagne.
