Leudwinus died on the 29th of September 722 at Reims. He was succeeded as Archbishop of Treve by his son, Milo, who brought his father's remains to Treve for burial. However, local customs prevented this, so Leudwinus' family decided to let the dead saint choose his own place of burial. His coffin was placed on a ship without a crew. It sailed by itself first to
Moselle, then
Saar, and finally docked at
Mettlach, where the church bells began to ring. Leudwinus was buried in St. Mary's Church at the Abbey at Mettlach. In 990, St. Mary's Church was replaced by a new structure called the Old Tower, the oldest preserved stone building in Saar. In 1247, Leudwinus' relics were transferred to the newly constructed Leudwinus Chapel (
Liutwinuskapelle). Some 200 years later, his remains were reburied again in a new chapel connected to the abbey church. During the
French Revolution, the monastery was purchased by the Boch family, who had the building demolished and built Liutwinus Cathedral in Mettlach, where the relics of the saint are located today. Reports of miracles at Leudwinus' grave in Mettlach have made it a popular pilgrimage site over the centuries. Records from Leudwinus' time as bishop are collected in the
Gesta Treverorum. ==Feast Day of St. Leudwinus==
