The picturesque little town of Sirmione sits at the end of a long promontory reaching out into the lake from its southern shore. It's hard to find a more charming entrance to a town - across a moat on a drawbridge and into the forecourt of a castle that looks as though it had been built for a movie set. The water-surrounded fortress was constructed in the 12th century by the Scaligeri, Verona's ruling family, as part of their defensive network against Milan and was later maintained by the Venetian empire. Tour its restored interior and climb the tower for panoramic views of the lake and town. Before the Scaligeri, the Romans came here to bathe in the sulphur springs, which are now the basis of a luxury spa.
