The Rocca di Sarteano is one of the most fascinating landmarks of the Sienese Val di Chiana and overlooks the village from the top of a mighty travertine spur, surrounded by a dense forest of centuries-old holm oaks which for centuries contributed to its impregnability. Today, this striking fortified complex stands as one of the principal testimonies to the medieval and Renaissance history of Sarteano.

The first documented references to the castle date back to 1038, although the presence of a fortified settlement is likely to be earlier. For a long time, the fortress served as the administrative centre of the region and belonged to the Manenti Counts, a powerful feudal family linked to the Empire. In 1178, Emperor Frederick I Barbarossa confirmed the Manenti family’s ownership of the fiefdom, which they retained until the 13th century.

Thanks to its strategic position between Siena, Orvieto and Perugia, Sarteano was often caught up in the political strife of medieval Italy. In 1379, the village became definitively allied with the Republic of Siena and the fortress was transformed into one of the most important defensive structures in the Sienese territory. Between 1467 and 1469, the castle was radically renovated by craftsmen and architects of the Sienese school, including the famous Lorenzo di Pietro, known as il Vecchietta, taking on the appearance that still characterises the complex today.

During the 16th century, the fortress was further adapted to meet new military requirements. The innovations brought about by firearms necessitated major defensive alterations, and the old medieval fortress was transformed into a modern military citadel inspired by the designs developed by the architect Baldassarre Peruzzi. More robust ramparts were built, along with quarters to house garrisons armed with arquebuses and a network of underground tunnels connecting the fortress to the village gates.

The fortress withstood numerous sieges, including that led by Cesare Borgia in 1503 and that by Spanish troops in 1552. After the fall of the Republic of Siena, the castle came under the rule of the Medici and in 1617 was granted in perpetuity to Brandimarte Fanelli and his descendants, who retained it until 1997.

The interior of the keep is arranged over four levels, culminating in a panoramic terrace offering spectacular views over the hills of the Val di Chiana and the Val d’Orcia. One of the most striking features is the extraordinary spiral staircase in travertine, comprising 134 steps. This structure runs vertically through the keep and served as the last means of escape in the event of a siege, connecting the upper floors directly with the exterior of the fortification.

Today, the Rocca di Sarteano is owned by the local council and, following extensive restoration work, has once again become one of the region’s leading cultural attractions. In addition to historical and scenic tours, the castle and the large park surrounding it host cultural events, historical re-enactments, performances and food and wine festivals throughout the year, showcasing the traditions of southern Tuscany.
