The history of the castle is linked to the Collalto family, of very ancient Lombard origin, who settled here from Treviso between the 12th and 13th centuries, founding both the castles of Collalto and San Salvatore. The second expanded rapidly: towards the end of the Middle Ages it became one of the largest in northern Italy, with thirty thousand square meters between fortress and village. Unconquered throughout the Middle Ages, during the long Venetian pax the castle saw the flowering of an extraordinary artistic season, with the arrival of painters, poets, musicians and writers. The Old Chapel bears witness to this: in fact it welcomed the extraordinary cycle of frescoes by Pordenone, while the palaces were enriched with works by the great Venetian masters of the time. The beauty and magnificence of the castle also became the backdrop for famous paintings by Cima da Conegliano.
With the advent of the Great War, the Piave was the backdrop to the last battles and the castle became the target of Italian artillery. Count Rambaldo, however, initiated a passionate phase of recovery of the extraordinary historical and artistic heritage that continued until the threshold of the new millennium, in which the castle of San Salvatore and its lands were definitively returned to history in all their splendor.
