The ancient medieval village of San Gregorio da Sassola with its magnificent castle is located just over 2 km from Torrino dei Gelsi. The village stands on a striking tuffaceous spur that accentuates its typically medieval appearance. The structure of the village is divided into two parts: the "Borgo Vecchio" of medieval layout overlooked by the imposing Brancaccio Castle and the baroque "Borgo Pio" built following the plague of 1656 at the behest of Cardinal Pio of Savoy. The history of San Gregorio da Sassola is closely linked to the Brancaccio Castle whose origins date back to the middle of the 10th century.The castle is still well preserved today.
