The Province of Sondrio is a fascinating mix of different styles and eras.
It is known as a place where man demonstrated his ingenuity by terracing the rugged lands that host its renowned vines. Enclosed within the heart of the Alps, the Province occupies the northernmost part of the Lombardy Region. Lying at opening of Valmalenco, Sondrio is in the Valtellina center. Typical are the vineyards sprawling over the foothills below the Rhaetian Alps. For centuries, the valley's northern slopes have been cleared of woods and rocks to terrace and cultivate these vines (both an economic and cultural asset of the Valtellina). They are an extraordinary testimony to man's ability to transform nature and terrain, despite unfavorable local and climatic conditions.
