In 1034, duke of Normandy Robert the Magnificent, who went to England, weathered such a big storm that he promised to found 3 chapels dedicated to Virgin Mary if he escaped alive. The sun came back... and our duke was safe! So he began the construction of the chapel and soon, a pilgrimage dedicated to the Virgin took place here.
An earthquake destroyed the chapel in 1538, but... miracle! The Virgin Mary's altar wasn't damage! Pilgrims came in a body in order to pray on it... But they had to rebuild the chapel. And for that, they needed the consent of the owner of the land, a lady called Mrs. de Montpensier: of course, she accepted and gave 8 oaks in the nearest forest in order to build the framework.
In 1613, the new chapel was completed. And when the Revolution came, Honfleur inhabitants, very fond of their Our-Lady church, organized a petition to save it from the destruction. But it was sold... the mayor decided to own it but, too late! They transformed it into... an inn! My god, sacrilege!
