In 1830, following the abdication of Charles X and his son, Louis-Antoine, Duke of Angoulême, the Bourbons left France forever and the throne on which they had reigned for over two centuries.

The road to exile, after touching Scotland and Bohemia, brought the royal family to Gorizia, then part of the Austrian Littoral region. A deep bond was immediately established with the small town on the banks of the Isonzo, which welcomed the prestigious guests with affection and kindness, consolidated by the choice of Charles X and his descendants to designate the Franciscan monastery of Castagnevizza, now in Slovenian territory, as the site of the family burial place.
