English: The choir during an Armenian Apostolic liturgy in the westwork of the Roman Catholic Basilica of Saint Servatius in Maastricht, Netherlands. The service was part of the 2018 Heiligdomsvaart ("relics pilgrimage"), a religious and historic event that takes place once in seven years and dates back to the Middle Ages. The Armenian Christians have a special relationship to Saint Servatius (†384), the Armenian-born bishop, missionary and patron saint of Maastricht.
