Remaclus was a 7th-century Benedictine monk, missionary bishop, and abbot. Born in the Duchy of Aquitaine, he studied under Sulpitius the Pious before joining the Abbey of Luxeuil in 625. He played a central role in establishing monastic communities, serving as the first abbot of Solignac and later leading the double-monastery of Stavelot-Malmedy. As the Bishop of Maastricht, he worked to expand monasticism in a challenging region, mentoring several notable spiritual figures during his tenure.
