Saint Hadelin was a 7th-century monk of noble birth who played a significant role in spreading Christianity within the region of modern-day Belgium. Originally from Guyenne, he served at the court of Sigebert of Austrasia before dedicating himself to monastic life. Studying under Remaclus at several abbeys, he later accompanied his mentor to Maastricht. He is primarily recognized for his missionary efforts and for establishing monastic communities, including the monastery at Celles and another at Visé, before retiring to a life as a hermit.
Monastic life
After his early education at Solignac and Cougnon, Hadelin joined the Stavelot Abbey. Following Remaclus's appointment as bishop of Maastricht in 651, he moved to that location. He later collaborated with Remaclus and Pepin of Herstal to establish the monastery at Celles near Dinant. After founding a second monastery in Visé, he spent his final years living as a hermit near Dinant, where he passed away around 690.
Veneration and legacy
He is particularly honored in the Namur diocese as the founder of Celles, where he serves as patron. In religious art, he is often depicted with a dove. Devotees invoke his name to help with ailments affecting children. A silver shrine in the Mosan style is kept in Visé, and his liturgical feast is observed on February 3.
