Adalbert of Egmond was a Northumbrian missionary active during the late seventh and early eighth centuries. Born into the royal family of Northumbria, he traveled to the European continent to assist Willibrord in spreading the gospel throughout Frisia and Holland. He eventually served as the Archdeacon of the See of Utrecht and became closely linked to the settlement of Egmond, where he spent his final years.
Life and mission
After potentially studying in Ireland, Adalbert joined Willibrord's mission around 690. The two missionaries landed near Domburg to begin their work. Adalbert's efforts were centered in the region of Egmond, where he eventually died. Local tradition suggests he protected the coastal settlement from pirates by summoning a thick fog to obscure the area.
Veneration and legacy
He is honored as a saint, with his feast day observed on 25 June. Following his death, a church was constructed over his tomb. His memory was preserved through Egmond Abbey, the first Benedictine monastery in the region. Although his relics were moved to Haarlem after the Reformation, they were returned to the re-founded abbey in 1984.
