Prestigious historic estate with a manor house, chapel, annexes, and farmhouses for sale in Buonconvento, Siena. Nestled in one of the most evocative and unspoiled areas of the province of Siena, the hamlet enjoys extraordinary views and is located about 5 km from the Via Cassia and consequently the Via Francigena as well as the town of Buonconvento, and is approximately 18 km from Montalcino. The famous Benedictine Abbey of Monte Oliveto Maggiore, dating back to 1320, borders the estate. Having belonged to various prominent families before falling under the dominion of the Piccolomini, the property was purchased in the early 1900s by Raffaello Ricci, the great-grandfather of the current owner. Notably, Saint Albert, the patron saint of Colle di Val d'Elsa, was born here in 1135. Access is granted via a classic country road that guarantees absolute privacy while preserving the ancient charm of the location. The property consists of an imposing terracotta manor house whose current design dates back to the 1500s. It spans four levels for a total of 1,249 sq mt/13,444 sq ft and is divided into two wings: the main residence, featuring a monumental entryway where a majestic cast-iron staircase, illuminated by a skylight opening onto an elegant cross vault, connects the formal reception rooms, large dining rooms, and bedrooms overlooking the countryside; and the estate manager's quarters, connected via an internal door, which formerly served as the residence for the farmer. Adjacent to the villa is a beautiful limonaia (lemon house) that supports a large panoramic terrace, an ancient granary recently restored as an open-plan event space, a warehouse, a consecrated church, and additional minor annexes. The estate also includes four large, independent farmhouses located a short distance away, all requiring complete restoration. The main buildings are surrounded by a well-kept formal Italian garden and lawn areas that would be ideal for adding a swimming pool, a lounge space, and other relaxation zones. The estate extends over an impressive 243 hectares of land, divided into arable land, woodlands and pastures, 18 hectares of olive groves, and precious, producing truffle grounds. This prestigious historic residence is the perfect property for a luxury hospitality investment or for establishing a premier agricultural estate in Tuscany
