Siena, the perennial rival of Florence, may not equal its neighbour to the north in sheer artistic achievement, but its charm and exuberance is all its own. The center of town is dominated by the Piazza del Campo around which every summer the Palio, a no-holds-barred horse race, is run to the delight of locals and tourists alike. Siena is also home to an unusual cathedral, which still sports the initial foundations of a massive planned expansion of the building that was cut short by the arrival of the plague. And of course, all of this is best seen while munching on one of the local ricciarelli, almond-based cookies.
