Sondrio is a town and comune located in the heart of the Valtellina. Wine represents one of the main resources of this region, together with tourism, especially in winter. The heart of Sondrio is its central Garibaldi Square. Not far from it is the Palazzo Sassi, that is home of the Art and History Museum of Valtellina. In a dominant position, near the ancient road to the Valmalenco, linking the town to Switzerland, stands the Masegra Castle, housing the Historical Museum of the Grisons Domination. Other sights include the Torre Ligariana, once the collegiate's bell tower, and the Palazzo Pretorio, once the seat of the Grisons government. In 2007, Sondrio was given the Alpine Town of the Year award.
