The Radicofani Fortress overlooks one of Tuscany’s most spectacular landscapes. Perched on a mighty basalt cliff at an altitude of 896 metres, at the highest point of the Val d’Orcia, this imposing structure has for centuries been one of the most important defensive strongholds in central Italy and still offers extraordinary views stretching from the Val d’Orcia to Monte Amiata, right up to the borders between Tuscany, Lazio and Umbria.

The origins of the fortification date back to the Early Middle Ages. In 978, the castle passed to the monks of Abbadia San Salvatore, who held it until 1153, when it was acquired by the Papal States. Its strategic position along the Via Francigena immediately made it a site of great military and political value. It was Pope Adrian IV himself who reinforced its defences to counter the advance of Emperor Frederick Barbarossa across the peninsula.

Over the centuries, the fortress was at the centre of disputes between the Papacy and the Republic of Siena, but the figure who more than any other fuelled its legendary charm was Ghino di Tacco. In 1297, the famous ‘gentleman bandit’ captured the fortress and made it his base for about three years. His exploits, halfway between history and legend, earned him such fame that he is remembered both by Dante Alighieri in the Divine Comedy and by Giovanni Boccaccio in the Decameron.

In 1411, the fortress came under the control of the Republic of Siena, which further strengthened its defences. The decisive turning point came in 1458, when Pope Pius II officially gifted Radicofani to the Republic of Siena. During the war between Siena and Florence, the fortress became one of the last and most important strongholds of the Sienese resistance. After lengthy sieges, the flag of Balzana was lowered on 17 August 1559, marking the end of the Republic of Siena’s independence.

Subsequently, Cosimo I de’ Medici entrusted the architect Baldassarre Lanci with the task of transforming the old medieval castle into a modern Renaissance fortress, equipped with mighty bastions and defensive structures that were state-of-the-art for the time.

Today, the Fortress of Radicofani stands as it did at the end of the 16th century and is one of the most visited monuments in the Val d’Orcia. The tour takes visitors through evocative underground passages, ramparts, courtyards and panoramic walkways up to the keep and the main tower, which houses an interesting archaeological museum displaying finds from the local area dating from the Bronze Age to the Middle Ages.

As well as its historical significance, what makes the Radicofani Fortress truly unique is the view. From its walls, you can enjoy a spectacular vista that takes in much of southern Tuscany, offering one of the most picturesque views of the entire Val d’Orcia, a UNESCO World Heritage Site.
