Nine years ago, Stefano Casiraghi Borromeo arrived as one of the most anticipated royal births in Europe. On February 28, 2017, Pierre Casiraghi and Beatrice Borromeo welcomed their first child, a golden-haired boy destined to carry forward two of the continent’s most storied lineages, the Grimaldis of Monaco and the Borromeo family of Italy.
From the very beginning, Stefano has embodied that distinctive mixture of royalty and warmth that so defines his parents. While his position places him firmly within Monaco’s inner circle, it is in the tender moments with his mother that we see a different side. Beatrice’s affectionate gestures, a gentle embrace, a protective glance, and a quiet word in his ear reveal the close bond they share and offer rare glimpses into their private world.
A name steeped in history
In royal families, names carry significant meaning. Stefano was chosen in tribute to his paternal grandfather, Stefano Casiraghi, the husband of Princess Caroline, who tragically lost his life in a boating accident in 1990 while competing to defend his offshore world championship title. His passing left a profound mark on Monaco and on his young family.

A familiar face on Monaco’s National Day
Although Pierre and Beatrice carefully safeguard their children’s privacy, Stefano has become a cherished presence during Monaco’s National Day celebrations. Standing on the balcony of the Prince’s Palace alongside his cousins, dressed in a classic coat, he often captures attention with his spontaneous waves and candid expressions.

Blue blood on both sides
As the grandson of Princess Caroline, Stefano is part of the Grimaldi dynasty and a great-grandson of Grace Kelly, one of the most iconic princesses in modern history. Yet his maternal roots are equally remarkable.

Isola Madre, Isola Bella and San Giovanni form a picturesque archipelago that remains under the family’s care. It was in this extraordinary setting that Pierre and Beatrice celebrated their religious wedding, surrounded by centuries of art, history and tradition.
The role of big brother
Stefano’s reign as the youngest was brief. In 2018, his brother Francesco Carlo Albert was born, and in October 2025, the family welcomed a daughter, Bianca Carolina Marta. With her arrival, Stefano embraced his role as the eldest of three.
