Collen was a 7th-century monk who is traditionally identified as the namesake of Llangollen in Wales. Before entering religious life, he reportedly served as a soldier in foreign lands. After his military service, he traveled to the area by coracle and established a church near the river. While his exact origins remain uncertain, some traditions link him to Cornwall or Brittany, and legendary accounts suggest he served as the Abbot of Glastonbury.
Life and legend
According to the Buchedd Collin, he was the son of Gwynawc. After traveling extensively, he returned to Britain to lead the monastery at Glastonbury. In these legends, he used holy water to drive the King of the Tylwyth Teg, Gwyn ap Nudd, and his followers away from Glastonbury Tor. He is believed to have passed away on 22 May.
Veneration and legacy
He was interred within the chapel he founded, which was known for centuries as the Old Church. Although he is primarily associated with Wales, the presence of churches dedicated to him in Cornwall and Brittany suggests a wider influence. His name survives through the town of Llangollen, which derives its name from his identity.
