A property that was sought after by some of the most important Sienese families, Poggio Bonelli has belonged to numerous different families throughout the centuries. It was first owned by the Spennali family during the Middle Ages, and passed into the hands of the Piccolomini family in the second half of the 16th century. In the following century, probably for dynastic reasons, it became the property of the Landucci family; and at the beginning of the 21st century it came to belong to the Banca Monte Paschi di Siena, the most ancient Italian bank in the territory of Siena.
The wine estate is owned by the Banca Monte Paschi di Siena, which acts as shareholder, while the management is carried out by a team of professionals with long-standing experience in wine-making. The end result is a human, dynamic, and solid business.
