The Shell Detectives: How Tiny Fossils Hold the Oceans Past

Known as the "Pearl of the Lake," Sirmione is a picturesque town on a long, narrow peninsula at the southern end of the lake. It’s famous for its well-preserved Scaligero Castle (Castello Scaligero), a rare lakeside fortress, and the Grotte di Catullo, the remains of a vast Roman villa. Visitors also enjoy its thermal baths and the beautiful Jamaica Beach with its flat rock slabs.
