Torrita di Siena is an ancient village lying on the western side of a hill in the Val di Chiana with a population of about 7000 people. Inside the town, St. Flora and St. Lucilla's church and St. Croce's church can be admired.

Although there is evidence of the Etruscan and Roman presence in Torrita, the town was cited in the historical documents only since 1037.
Originally, the current chief town was a small village that became a "castrum", namely a fortified village, in the Middle Ages. In effect, under the protection of the Republic of Siena, this small town emerged as one of the defensive bastions against the Florentine front, represented by the castle of Montepulciano. At the time, the castle of Torrita was surrounded by a huge fencing wall with three gates (Porta a Gavina, Porta a Pago and Porta a Sole) to which one more gate was added in the XIX century.
In the last centuries of the Middle Ages, many battles were fought below the walls of Torrita. Some of the most memorable deeds are remembered in the frescoes inside the Sala del Mappamondo of the Palazzo Comunale. With his painting ability, Lippo Vanni fixed in history the episodes concerning the castle of Torrita and the Val di Chiana in the centuries-old fight between Siena and Florence.
In 1528 the city defences needed reinforcement works to stem the numerous damages suffered during the continuous sieges.
With the arrival of Charles V's Spanish troops, the territory of Siena was completely annexed by the Medicis, allies of the king.
Therefore, Torrita became part of the Tuscan Grand Duchy in 1557. Its surrender is one of the most important events of the campaign aimed to conquer the territories of the Republic of Siena.
In the XVIII century, the "barn of Siena", as Torrita had been called for the centuries before, became a very rich and productive agricultural area after the reclamations in the Val di Chiana ordered by the Grand Duke Pietro Leopoldo.
In the XX century, the agricultural activity was supported by a flourishing industrial activity.
