Fun Facts About Saint Nicholas Cathedral in Monaco, the Burial Place of the Grimaldi Family


Saint Nicholas Cathedral in Monaco is not just a place of worship; it is a treasure trove of history, tradition, and devotion deeply connected to both the Monegasque populace and the ruling Grimaldi family. The cathedral serves as an embodiment of Catholic heritage and is an intriguing point of intersection between spirituality, art, and history. Let’s delve into some fascinating facts about this esteemed establishment, illuminating its historical, theological, and cultural significance.

The Cathedral’s Name Change Over Time

From Saint Nicholas to the Immaculate Conception and Back

The original church on the site was dedicated to Saint Nicholas, the patron saint of sailors and children. After the original 13th-century structure fell into disrepair, the new cathedral was constructed from 1875 to 1903 and dedicated to the Immaculate Conception. However, it reverted to being called the Cathedral of Our Lady of the Immaculate Conception and Saint Nicholas (Cathédrale Notre-Dame-Immaculée), honoring both titles.

Theological Significance

The Immaculate Conception refers to the belief in the Catholic Church that the Virgin Mary was conceived without original sin, a dogma solemnly defined in 1854 by Pope Pius IX. The Catechism states, “The most Blessed Virgin Mary was, from the first moment of her conception, by a singular grace and privilege of almighty God and by virtue of the merits of Jesus Christ, Saviour of the human race, preserved immune from all stain of original sin” (CCC 491). This name change embodies the growing emphasis on Marian devotion in modern Catholicism.

An Architectural Gem of Neo-Romanesque Style

The cathedral is a splendid example of neo-Romanesque architecture, characterized by rounded arches and simple, sturdy pillars.

The Influence of Monastic Tradition

This architectural style is reminiscent of medieval monastic architecture, connecting it to a long history of Catholic contemplative practice. It seeks to evoke a sense of timelessness and divine order, inviting visitors to turn their thoughts toward the eternal.

The Cathedral Houses the Remains of Saint Devota

The Patron Saint of Monaco

Saint Devota is the patron saint of Monaco and Corsica. According to tradition, her relics were brought to Monaco in 1070 AD, and they now rest in the cathedral.

Theological Significance

The presence of the relics reinforces the Catholic belief in the Communion of Saints. As per the Catechism, “Being more closely united to Christ, those who dwell in heaven fix the whole Church more firmly in holiness…They do not cease to intercede with the Father for us” (CCC 956).

The Resting Place of the Grimaldi Family

One of the most striking facts about the cathedral is that it serves as the burial place for the Grimaldi family, the ruling house of Monaco. This includes Prince Rainier III and his wife, Grace Kelly.

Significance of the Royal Burial Tradition

In the Catholic tradition, burial in consecrated ground is considered a spiritual benefit, as it allows the deceased to rest in sanctified soil, awaiting the resurrection. The Catechism notes that “the bodies of the dead must be treated with respect and charity, in faith and hope of the Resurrection” (CCC 2300).

The Tradition of the “Grand Blessing of the Sea”

A Unique Local Custom

Every year, the Archbishop of Monaco performs the “Grand Blessing of the Sea,” a procession from the cathedral to the harbor.

Theological Significance

This tradition is in keeping with the universal Catholic emphasis on sacramentals, which are “sacred signs which bear a resemblance to the sacraments” (CCC 1667). In this case, the blessing of the sea symbolizes God’s dominion over creation and His providential care.

A Musical Landmark: The Grand Organ

Installed in 1976, the Grand Organ of the cathedral has 7,000 pipes, making it one of the most impressive musical instruments in the region.

The Role of Music in Catholic Worship

Music plays an integral part in the Catholic liturgy. Saint Augustine, one of the great Church Fathers, said, “He who sings prays twice.” The Grand Organ adds a dimension of solemnity and grandeur to the worship experience.


Saint Nicholas Cathedral is not merely an architectural marvel; it’s a multi-dimensional tapestry woven with threads of history, culture, and theology. From its unique name and stunning neo-Romanesque architecture to its role as a royal burial ground and a venue for sacred music, this cathedral encapsulates the richness and depth of Catholic tradition in a microcosm.

The cathedral exemplifies the richness of the Catholic faith, not just as an institution but as a living, breathing entity, deeply interwoven with the life and history of Monaco and the Grimaldi family. It stands as a testament to the enduring relevance and vitality of Catholic tradition in the modern world.
