The largest Italian lake, Lago di Garda or Bènaco (until 800 A.D. Lacus benacus) is located in the three Italian regions Trentino-Alto Adige (north), Lombardy (west) and Veneto (east). The lake is almost 52 km long and over 17 km wide and covers an area of around 370 square kilometres. The large body of water has a positive influence on viticulture. Due to its location, the climate is sub-Mediterranean, with hot summers and mild winters with little precipitation. Around the lake, vines are cultivated in the north and olive trees and citrus fruits in the east and south. There are many DOC/DOCG areas directly on or near the lake, some of which cross regional borders. These are Garda, Lugana and San Martino della Battaglia (Lombardy and Veneto), Garda Colli Mantovani, Riviera del Garda Bresciano and Valtènesi (Lombardy), and Valpolicella or Amarone della Valpolicella and Recioto della Valpolicella (Veneto).
