Detail of the theme float used in the procession of the 2018 <i>Heiligdomsvaart</i> (Relics Pilgrimage) in Maastricht, Netherlands, with a glass mosaic showing the reliquary bust of Saint Servatius. The history of this seven-yearly pilgrimage goes back to the Middle Ages. The first 'modern' version took place in 1874. On both Sundays of the 10-day festival, a procession is held in which the main relics and other devotional objects are exhibited. This photo was taken shortly before the start of the (first) procession on Sunday 27 May 2018.
