The austere castle built in the Longobard period on an ancient Etruscan and later Roman site and demolished in 548 D.C.by Totila’s Goths, was, by the 11th century, already considered as impregnable. It reached its maximum splendor in the Late Middle Ages due to its military might and for religious reasons. Originally composed of a fortified nucleus and a monastery, it was the noble home of the Scifi’s, Counts of Sassorosso, a family of imperial origin in the court of Frederick II, to whom the Emperor conceded the castle as a feudal manor, and from whom Saint Clare of Assisi, of the Tancredi line, descends, a race of captains of war and of peace who held important offices in the Comune of Perugia and of the Montemelini. Toward the end of the XVth century, the manor passed to the Signorelli family, to become from 1699 - at this point already in ruin - the summer home of the Graziani, Baglioni and Ansidei families. It was later absorbed into the Pontifical State to which it belonged up until the period of the unification of Italy. Brought to complete ruin by a series of events, it is today returning to its antique splendor.
