Basilica of Notre-Dame de Boulogne

This classical architecture basilica rises 101 meters high with a 47-meter diameter dome, dominating the skyline of Boulogne-sur-Mer as a classified historical monument.

Construction began in 1827 under architect Benoît-Agathon Haffreingue after the original medieval cathedral was destroyed during the French Revolution in 1798.

The site has welcomed fourteen French kings and five English monarchs throughout history, establishing its significance as a major European pilgrimage destination since medieval times.

Visitors can explore the largest crypt in France, spanning over 100 meters in length, which requires approximately 1.5 to 2 hours for a complete visit.

The basilica was designed by a self-taught priest who drew inspiration from Saint Paul's Cathedral in London, Saint Peter's Basilica in Rome, and Les Invalides in Paris.
