The first historical references to the original structure of Piaggia date back to before the year 1000. The original building was a convent along the via Francigena, the storied pilgrimage route from France to Rome, which still crosses the estate to connect the towns of San Vivaldo and Montaione.
The farmhouse originally belonged to the noble Florentine family the Guicciardini Strozzi, who used the estate for hunting. It then passed to the Bardini family whose namesake museum can be found in Florence, before being bought by the Billeri family in the second half of the 20th century, and now to the Counts Passerin d’Entrèves et Courmayeur.
