Civitella in Val di Chiana (official name), often also Civitella di Val di Chiana, is a comune in the province of Arezzo, south of Arezzo in Tuscany, Italy. It is one of the best-preserved of the network of Lombard fortresses of the 6th and the 7th century in central Italy, strategically placed to control the whole territory. The characteristic elliptical shape of the military settlements can still be seen in the layout of the town walls.
