Boat Tour to Sirmione

Catullus called Sirmio the jewel of all islands and peninsulas around 55 BC, and the Roman villa that carries his name still spreads over some two hectares at the headland's northern tip. The Grotte di Catullo is the largest domestic Roman building surviving in northern Italy. Its name is a misnomer. Sixteenth-century visitors mistook the collapsed vaults and cryptoporticus for caves. A Boat Tour to Sirmione approaches this ruin the way antiquity did, from the water, where the terracing reads as a single stepped mass of olive groves and limestone. The peninsula runs roughly four kilometres into Lake Garda and narrows to a strip barely wide enough for one road. Mastino I della Scala fortified that neck around 1277. The Rocca Scaligera that resulted is unusual among Italian castles: it encloses a walled harbour, a darsena where the Veronese fleet could shelter behind swallowtail merlons. Boat Tour to Sirmione tours still pass within metres of that dock wall, which has changed little since the della Scala family lost the lake to Venice in 1405. Its lakefront curtain is among the best preserved in the Scaligeri chain that runs north to Torri del Benaco and Malcesine. Beneath the surface lies the other engine of the town. The Boiola spring rises about three hundred metres offshore at a depth of some twenty metres, delivering sulphurous water at close to sixty-nine degrees Celsius. Engineers first captured it in 1889, and the thermal trade it created turned a fishing village into a spa town within a generation. Boat Tour to Sirmione tickets sold today follow a route that was first commercial, then medicinal, and only later scenic. What survives is a rare compression of periods. A Roman villa, a Scaligeri fortress, a nineteenth-century thermal industry and a medieval parish church, San Pietro in Mavino, all within a short walk of each other on a strip of glacial moraine. Lake Garda, at 370 square kilometres the largest lake in Italy, supplies the frame. Seen from a Sirmione peninsula boat cruise, the town resolves into its true shape — not a village on a shore but a fortified line drawn out into open water, with the southern foothills of the Alps closing the horizon behind it. Few Lake Garda landmarks read so clearly from the deck of a Boat Tour to Sirmione.
