The St. Michael and St. Gudula Cathedral is a Roman Catholic church at the Treurenberg hill in Brussels, Belgium. In French, it is called Cathédrale Saints-Michel-et-Gudule and in Dutch Sint-Michiels- en Sint-Goedelekathedraal, usually shortened to "Sint-Goedele".
In 1047, Lambert II, Count of Leuven founded a chapter in this church and organized the transportation of the relics of Saint Gudula, housed before then in Saint Gaugericus Church on Saint-Géry Island. The patron saints of the church, archangel St. Michael and the martyr St. Gudula, are also the patron saints of the city of Brussels.
In the thirteenth century, the cathedral was renovated in the Gothic style. The choir was constructed between 1226 and 1276. The façade was completed in the mid-fifteenth century.
It is an archiepiscopal cathedral of the Archbishop of Mechlin-Brussels, the Primate of Belgium, currently Archbishop André-Mutien Léonard. It is located in the national capital and therefore often used for Catholic ceremonies of national interest, such as royal marriages and state funerals.
The south tower contains a 49-bell carillon by the Royal Eijsbouts bell foundry on which Sunday concerts are often given. The dimension of cathedral building is; overall length 114 m, implemented length 109 m, exterior width at the chorus 57m, interior width 54m, height of towers 64m.
