Thank you for the nice question. Before becoming “Isola Isabella” (later shortened to Isola Bella), this island in Lake Maggiore was known as Isola Inferiore (or “Lower Island”). The name change dates back to the 17th century when Carlo III Borromeo began the transformation of the island and dedicated it to his wife, Isabella d’Adda. The name “Isabella” was subsequently contracted into the more melodic “Isola Bella.” 😊 A quite romantic story!!
