The town of Manciano is in the province of Grosseto and has a population of about 7500 inhabitants. The Rocca Aldobardesca stands out to defend its imposing medieval castle, while the Porta Romana outside the town was the passage to reach the Baths of Saturnia. The Torre dell'Orologio can be visited in the town of Manciano.

As can be seen in the Prehistory and proto-History Municipal Museum, the human settlements in the area of Manciano date to archaic epochs and regard the tribes of nomadic hunters, mainly. A permanent settlement took place with the Etruscans. They left the archaeological site of the necropolis of Marsiliana and of Pian di Palma as heritage. The modern town of Manciano, which was a big built-up area in the ancient times, got its name from the Mancia "gens" who inhabited it after the Roman occupation.
In the middle centuries of the Middle Ages, the territory of Manciano was the upright dominion of the counts Aldobrandeschi, some Lombard-born feudatories from the Germanic Empire. It was thanks to them that the construction of the massive stronghold was started with the aim to garrison the area, which was strongly contended for by other powerful cities. In effect, the inhabitants of Manciano had to defend their town from Orvieto, first, and from the expansion views of the counts Orsini and of Siena, later. The last two allied and in the XV century and drove Manciano's much desired autonomy away.
In 1555, what remained of the Republic of Siena entered the Tuscan Grand Duchy. Manciano gave life to the town hall of Saturnia and Capalbio together with other villages of the valley of the Albegna. Manciano became one of its richest and most populated agricultural centres, also because it benefited from its high position, that kept it away from the malaria-stricken areas and from the marshy Maremma's zones. It conquered its autonomy at the half of the XVIII thanks to the territorial reform by Pietro Leopoldo of Lorraine.
