In Monaco, you will hear people speak French and live much the same life of those in surrounding France in most respects, but they are certainly more religiously inclined than those in neighbouring France. Not only is The Solemnity of the Immaculate Conception an official holiday here, but Roman Catholicism itself is declared the state religion in Monaco’s constitution.

About 95 percent of Monaco’s population identifies as Roman Catholic, and many of them celebrate Immaculate Conception with devotion and seriousness. They may attend services at The Cathedral of Our Lady of the Immaculate Conception on Saint Martin Avenue and listen to the amazing cathedral choir there.

And they may also have a festive family dinner at home and gather with friends and relatives to celebrate the meaning of the day, which is the belief that Mary was conceived without sin in order to allow her to later conceive Jesus Christ without sin.
