Originally a simple church, it was given the title of minor basilica by Pope Pius X in 1904.
Lille Cathedral is a Roman Catholic church and basilica located in Lille, France. It is the cathedral church of the Archdiocese of Lille.
The church was built in honour of the Virgin Mary and takes its name from a 12th-century statue of the saint that has miraculous properties ascribed to it.
In 2008, following the reorganization of the ecclesiastical provinces of France, the diocese of Lille was elevated to the status of a metropolis and the cathedral became a metropolitan cathedral, the seat of the Archbishop of Lille.
The cathedral was built in stages under the direction of several generations of architects from 1856 to 1975. It was completed in 1999 by the installation of a modern facade, with part of the initial program having been abandoned.
