Peschiera del Garda is a town and comune in the province of Verona, in Veneto, Italy. When Lombardy-Venetia was under Austrian rule, Peschiera was the northwest anchor of the four fortified towns constituting the Quadrilatero. The fortress is on an island in the river Mincio at its outlet from Lake Garda. The town is encircled by massive Venetian defensive systems that have been a UNESCO World Heritage Site since 9 July 2017.
