Trudo was a seventh-century monk and abbot who lived in the Hesbaye region. Born in Zerkingen around 629, he dedicated his life to religious service, studying under the Bishop of Metz at the Church of St. Stephen. After his ordination, he returned to his home district to preach the Gospel. He established a church at Sarchinium, which eventually grew into the monastery that became Sint-Truiden Abbey. Because of his extensive missionary work in the area, he is remembered as the Apostle of Hesbaye.
Life and work

After receiving his education, Trudo founded a church on the River Cicindria, which was blessed by Theodard of Maastricht around 656. This site served as the foundation for a monastery. He also established a convent for women at Odeghem, near Bruges. His religious efforts and preaching led to the formation of a community of disciples that expanded his influence throughout the region.
Veneration

Trudo was buried in the church he built, and his relics were moved several times, including a translation in 880. To protect them from Norman raids, his remains were hidden in a crypt. Although lost after a fire in 1085, the relics were rediscovered in 1169. He is commemorated in various traditions, with feast days observed on 23 November and 6 December.
