Cetona welcomes visitors with its majestic Piazza Garibaldi. This large square piazza was constructed in the mid-sixteenth century by the marquis Vitelli, who wanted to create a new entrance to the town, one that would really show off its architecture. The piazza is surrounded by the churches of Santissima Annunziata and San Michele Arcangelo, and by the Terrosi and Vitelli palazzos.
The town hall is home to the Civic Prehistory Museum of Monte Cetona. This museum documents the various stages of human settlement in the Monte Cetona area, from the Paleolithic era to the end of the Bronze Age. Neanderthal man lived in certain caves around Cetona, leaving traces of himself in the landscape in the form of chipped stone tools and the remains of hunted animals. Populations came and went between the Neolithic era and the Copper Age, but human habitation soared in the second millennium BCE: nowhere was this more true than of Belverde, where people erected huts, lived under the lips of cliffs, and started to bury their dead. We have a wealth of archaeological records from this period, which makes up the nucleus of the museum.
