Known as the "Pearl of the Garda", Sirmione is located on the Lombard-side of Lake Garda. Already inhabited by people of the Bronze Age who left the remains of their huts built on stilts, the Romans made it a place for holidays. On the tip of the peninsula of Sirmione, there are the ruins of a huge villa, the "Grotte di Catullo" (Catullo's Caves), with frescoes dating back to the second century BC. Sirmione is a town in the province of Brescia, whose main industry is tourism due to the presence of Roman and medieval remains, and for its thermal waters.
