The mineral water spring, still bubbling to this day, doubtless led to a Roman settlement here, followed by other settlements and Roman villas. As a result, many ancient remains have been put to use in the later buildings of SAN PANCRAZIO. In the Middle Ages, a castle with surrounding houses and a church named the Castrum San Pancrazi was built. The surrounding walls and gate have not survived, but the main house of SAN PANCRAZIO dates from this period. At the beginning of the 18th century, the continually destroyed buildings were turned into a castle, and its present-day appearance. The church (CHIESA) was also rebuilt. After the dissolution of the Papal States at the beginning of the 19th century the property was converted into a farming village accommodating 6 tenant families. After careful restoration, the barn (FIENELE), pigsty (PORCILAIA) and other outbuildings are today as they were then.
