Built at the behest of Queen Margherita of Savoy, who had been staying in Gressoney as a guest of the Beck Peccoz barons since 1889, the castle stands at the foot of the Colle della Ranzola in the locality known as 'Belvedere', due to the splendid view that from there dominates the whole valley up to the Lyskamm glacier. The laying of the first stone of the building took place on August 24, 1899 in the presence of King Umberto I who, assassinated in Monza a year later, would not see the completion of the works, which lasted until 1904.
