The Martyrs of Gorkum (Dutch: Martelaren van Gorcum) were a group of 19 Dutch Catholic clerics and friars who were hanged on 9 July 1572 in the town of Brielle by militant Dutch Calvinists during the 16th century religious wars. Many miracles have been attributed to the intercession of the Gorkum martyrs, especially the curing of hernias. The beatification of the martyrs took place on 14 November 1675, and their canonization on 29 June 1867. For many years the place of their martyrdom in Brielle has been the scene of numerous pilgrimages and processions. The reliquary of their remains is now enshrined in the Church of Saint Nicholas, Brussels, Belgium.
