The Notre-Dame-de-Bon-Secours church
The Basilica of Notre-Dame de Bon-Secours, (formerly known as Notre-Dame-du-chêne-entre-deux-bois) is located in the very centre of Bon-Secours, a village on the French-Belgian border that is now part of Péruwelz, in the province of Hainaut (Walloon Region of Belgium). It is the centre of a Marian pilgrimage that began in the Middle Ages around an old oak tree dedicated to Notre-Dame-du-chêne-entre-deux-bois).
The present basilica, dedicated to the Virgin Mary, was built from 1885 to 1892 in neo-gothic style.
