The town of Civitella Paganico, founded in 1928, is in the province of Grosseto. With a population of about 3000 inhabitants, the territory first shows its suggestive street of Corso Fagarč, which wedges in the centre of Paganico between buildings dating to the XIV-XV centuries.

Civitella and Paganico, the two small towns that compose the city, were two of the agricultural Etruscan settlements along the river network on the Ombrone river that was navigable at the time. Thanks to the discovery of some graves richly furnished, the Etruscans' presence dates to the first half of the VI century B.C., and it lasted upright until the arrival of the Romans who came in this area two centuries later to transform it into one of the provinces of the future empire.
The paludification of the territory around the Ombrone and the Barbarian invasions depopulated it and erased most of the Etruscan-Roman constructions. Nevertheless, the second wave of invasions, which brought the Lombards into Italy around the VI century A.C., gave the territory a new life.
The new medieval strongholds rose and the new feudal seigniories, destined to intermingle with the Frank families, gave life to the Sienese nobility in the Middle Ages. One of these families, the counts Ardengheschi, took possession of the territory corresponding to Paganico. Their seigniory' presence was certified since the first year following the year 1000. This family had a certain Ardingo as its family leader, who, as it is known, was an official very near to the emperor Herny II and a protagonist of the Sienese policy in the first years of the XI century.
In 1193, the Republic of Siena included Civitella and Paganico within its jurisdiction and it assumed its direct control in the XIV century, keeping it until its annexation to the Tuscan Grand Duchy at the half of the XVI century. The area of the current town experienced the neo-feudalism period under the Medicean state, first, and the state of the Lorraine, later. In 1630, it was ceded to the Patrizi, members of the Florentine nobility who administered it until 1747.
The Leopoldine reforms at the end of the XVIII century, first, and its inclusion to the Kingdom of Italy, later, incorporated the two centres in the town of Campagnatico. This created many problems to the inhabitants of the two towns, because between them and the municipal seat there was a remarkable distance that was difficult to cover in a period between the XIX and the XX century, when very few people had fast transportation means. This is why Civitella and Paganico obtained their municipal autonomy in 1928 and created an independent administrative unity.
