Looking diagonally out over the extraordinary Piazza Garibaldi is the Cathedral of San Cerbone. The urban planning here is simply brilliant and the effect, as proposed by the church, goes against the usual architectural perspectives. Precisely for this reason, it is entirely unique.
The square in the historic center is surrounded by other important buildings such as the Palazzo del Podestà, the Palazzo del Comune, the Loggia del Mercato, and a little further on the Zecca (Mint).
Also in the center is the unmissable Fonte Pubblica (Public water source), known as the Source of Abundance. During a restoration in 1999, a fresco depicting the Tree of Fertility came to light from beneath a layer of plaster. It depicts a large tree from which twenty-five phallic symbols hang and two women scramble to collect them. According to the main interpretation, the fresco - dated between 1265 and 1335 - had an apotropaic function, that's to say, a good omen that the crops would be abundant.
In the upper part of the town, built during the period of Sienese domination, the mighty fortress of Torre del Candeliere stand tall with the best panoramic view of the area.
In addition to the rich heritage of the historic center, you can visit museums such as that of Sacred Art, the Archaeological Museum, the Mining Museum and the Antica Falegnameria.
