The city is the most radiant, noble and harmonious example of
medioeval urban planning and gothic architecture.
An only example: Piazza del Campo, by the form of a shell,
surrounded by buildings interrupted by the massive structure of Palazzo Pubblico, rich of exceptional testimonies of the figurative senese culture .
But beyond the great monumental complexes, Siena is an open sky museum with treasures behind every angle, all to be discovered.
