Originally built as the residence of the influential de Robertis family...

...at the turn of the sixteenth century by Capitano Giacomo de Robertis from Bologna, who was then in the employ of the Knights Hospitaller of St. John of Jerusalem, Rhodes and Malta (better known as Knights of Malta).

It later passed through marriage to the noble Testaferrata family and later still to the Marquis De Sain family. In 1967 it was converted to a hotel, with special care taken to preserve the elegance and character of the building's architectural beauty.
