The St. Michael and Gudula Cathedral is located at the Treurenberg hill in Brussels, Belgium. The church patron saints, archangel St. Michael and the martyr St. Gudula, are also the patron saints of the city of Brussels.
In 1047, Lambert II, Count of Leuven founded a chapter in this church and organized the transportation of the relics of Saint Gudula, before then housed in Saint Gaugericus Church on Saint Gaugericus Island. The south tower contains a 49-bell carillon by the Royal Eijsbouts bell foundry on which Sunday concerts are often given.
