Set in a commanding panoramic position between the rolling hills of Montalcino and the Maremma, this remarkable 12th-century castle combines more than nine centuries of history with one of Tuscany's most iconic landscapes. Originally founded as a monastic estate and later owned by some of the most influential families of the Republic of Siena, it still preserves frescoed coats of arms, monumental fireplaces, historic halls and exceptional architectural details.Protected by the Italian Fine Arts Authority, the entire estate is arranged around a charming inner courtyard with an ancient well, enclosed by its original defensive walls and surrounded by a park. The main building features elegant reception rooms, magnificent barrel-vaulted wine cellars, historic kitchens, beautifully decorated bedrooms and frescoed interiors. The property currently offers 20 en-suite guest rooms, while a separate building accommodates an additional 8 suites.A key strength of the estate is its fully approved redevelopment project, allowing renovation works to begin immediately without the lengthy planning procedures typically required for historic properties.The approved plans envision either an exclusive luxury boutique hotel or a prestigious destination dedicated to hospitality, culture and events. The project includes 24 suites, three restaurant dining rooms, new professional kitchens, the conversion of the Limonaia into a versatile multi-purpose venue, parking areas, an underground garage with nine parking spaces, and the possibility of creating additional independent apartments within the annex. The municipal swimming pool can also be obtained under concession.A truly unique opportunity to bring an international hospitality project to life in one of Tuscany's most authentic settings, just 10 km from Paganico, 30 km from both Montalcino and Grosseto, 50 km from Pienza and the Tuscan coast, 130 km from Florence and 200 km from Rome.
