The Basilique Notre Dame du Bon Secours, Marie Auxiliatrice (English: The Basilica of Our Lady of Refuge of Mary, the Help of Christians) is a Roman Catholic minor basilica in Bonsecours near Rouen, Seine—Maritime, France. It is the first church in France to be built in the Gothic Revival style. The basilica is highly ornately decorated with windows, sculptures and other elements often carrying the name or coat of arms of a patronal donor.
The original shrine was dedicated to the Blessed Virgin Mary, Help of Christians dating back to the thirteenth century. It was reconstructed and enlarged in 1840.
Pope Pius IX granted the decree of pontifical coronation to the venerated Marian image enshrined within on 15 July 1870. The former Archbishop of Rouen, Cardinal Henri-Marie-Gaston Boisnormand de Bonnechose executed the rite of coronation on 24 May 1880.
Pope Benedict XV raised the Marian shrine to the status of Minor Basilica by Pontifical decree Illustriores Inter Sacras on 27 March 1919.
