Rocca di Tentennano

Rocca di Tentennano is a limestone fortress perched on a steep rocky pinnacle above Val d'Orcia, featuring thick defensive walls and a pentagonal observation tower. The structure spans multiple levels and uses the natural shape of the hill as an additional defensive layer.

The fortress was controlled by Siena between 1250 and 1258, during which time the city strengthened its fortifications by reinforcing stones and replacing a damaged tower. These early reinforcements established it as a key defensive position in the region during the medieval period.

The fortress is closely linked to Saint Catherine of Siena, who sought refuge here in 1377 and developed her literacy skills during her time at the location. This connection has shaped how locals and pilgrims view the significance of this place.

The walk to the fortress entrance follows a cypress-lined path starting from a parking area at the base of the hill. The path is navigable on foot but requires moderate physical effort due to the steep incline.

Inside the fortress is a water system featuring a large cistern carved into the rock that collected rainwater during military operations. This water storage system reveals how carefully the defensive infrastructure was designed to withstand prolonged sieges.
