This large, church-shaped shrine once housed the relics of a 7th-century saint who served as a missionary and bishop to the western regions of present-day Belgium. St. Amandus (d. 679) also established a monastery at Elnon, near Tournai (western Belgium), where the monks later commissioned this reliquary to honor his remains. The shrine of St. Amandus, ornamented with silver columns and gilded apostles, was the focus of a strong local cult, visited by pilgrims who came for healing or in thanks for prayers answered. Given its large size and popularity, the shrine was probably placed upon a platform supported by columns behind the main altar for year-round veneration.
