Saluzzo

Saluzzo was a Piedmontese marquisate between the Alps and the Po. In 1337 Thomas of the del Vasto dynasty ruled the small state, which repeatedly clashed with Savoy.

In the 15th century Ludovico II had the Buco di Viso tunnel cut through Monte Viso to open a trade route. He resisted a Savoyard siege in 1486 with French help, yielded in 1487 and returned in 1490. France annexed Saluzzo in 1548; the Treaty of Lyon transferred it to Savoy in 1601.
