San Marino sits on Mount Titano inside central Italy, a tiny republic of three medieval towers, walls and stone lanes looking out over the Adriatic plain. The old town centre, the Guaita and Cesta towers and the Basilica of San Marino are the core of any visit, with the countryside and nearby Rimini and Urbino easy to add. Spring and early autumn bring the mildest weather and thinner crowds; summer is busy with day trips, and winter can be cold and foggy on the mountain.
