Loro Ciuffenna has about 5,000 inhabitants and it is rich in history and military medieval architectures. It is in the province of Arezzo and the Palazzo Venturi, the Museum dedicated to the local artist Venturino Venturi and the Parish of San Pietro a Gropina can be visited here.

Even if there are not any remarkable evidences, it is easy to hypothesize the Etruscan and Roman presence in this territory. Yet, the territory began losing its importance since the II century b.C., when Giulius Caesar concentrated the Roman financings on the foundation of Florentia (the modern Florence) with the aim to control an area where popular rebellions against the Etruscan aristocracy and the Roman dominion followed one another. The construction of the new Cassia way that was very far from the area of Loro further contributed to exclude the population of the town from the most important commercial routes.
The Lombards established their presence in the territory after the fall of the Roman empire. This population contributed to the flourishing of many areas that were almost depopulated in Tuscany in the need to link their capital, Pavia, to the powerful southern-central dukedoms. In the VIII century, when the Franks arrived, all the lands in Arezzo was scattered with the original nucleuses of the future big medieval castles. The castle of Loro had probably existed since the X century. the first document citing it dates to 1059. This castle first belonged to the Ubertini and then Guicciardo, the founder of the homonym stronghold not far from here, governed it. He was in contact with the feudatories Guidi as a member of the family or their vassal. The Guidi were among the protagonists of the fortification of the villages in the Casentino and the Valdarno after the year 1000.
Yet, the power and prestige of the bishopric of Arezzo strongly influenced the area and it played a remarkable role in the choice of the families that governed Loro.
In the XIII century, the Guidi's power weakened more and more because of the pressure of Florence that stipulated with them a treaty of free access to the town in 1219.Iin 1293, also the Guidi lost Loro and other castles. The fight between Guelphs and Ghibelline characterized the following century and the conflict between the Republic and the most powerful Ghibelline feudatories was part of this ambit. This was when the Guidi uselessly tried to conquer Loro again. From 1337 on, the situation became more balanced since Arezzo fell in the hands of Florence.
In the XV century, therefore, a new and rich class of landowners grew. In 1462, Loro became an autonomous town. The social and political situation of the territory, yet, changed in 1646, when Ferdinando II de' Medici gave it as a feud to Piero Capponi. At this time, Loro extended from its original nucleus near the castle up to beyond the stream Ciuffenna, but paradoxically, the area experienced a period of economic decline that also entailed violent revolts such as the one of 1799 against the French who had occupied the Grand Duchy following the orders of Napoleon. Anyway, it was the Unity of Italy in 1860 which caused a new general improvement of the area.
