Crepacore Castle, Norman fortress on Via Francigena near Faeto, Italy

Crepacore Castle stood on the summit of Monte Castiglione, an isolated height with steep flanks at 959 m above sea level in what is now the municipality of Faeto, between the Campanian Apennines and the Tavoliere delle Puglie. The medieval fortress, Latin Castrum Crepacordis, was probably built over the remains of an Irpinian-Samnite fortification; its walls are gone, and the site is now open ground. Less than 100 m from its northern foot runs the Via Francigena, following the line of the Roman Via Traiana.

The castle is first documented in 1024, when Byzantine emperors Basil and Constantine granted it with the hamlet of Crepacore to the bishop of Troia. Pope Alexander II confirmed the privilege in 1061 after the Norman conquest, and Paschal II renewed it in 1100. Under the Angevins, Charles I of Anjou restored the fortress and settled Provençal soldiers' families there in 1272.

The name Crepacore probably comes from Latin crepa(tum) cor, 'broken heart', or crepa(t) cor, 'one who strikes the heart', a nickname for a warrior. The toponym survives in the dialect of Celle di San Vito for a district about 600 m east-northeast of the Crepacore hamlet. The hamlet is also called San Vito after its chapel to Saint Vitus, rebuilt at the start of the third millennium.

The castle site lies on the summit of Monte Castiglione at 959 m, in the municipality of Faeto. The Via Francigena passes less than 100 m from the northern foot of the hill, and the Celone spring and the Crepacore hamlet with its rebuilt San Vito chapel stand about 400 m to the north-east. Approach on foot from these points; the slopes are steep and the summit is exposed.

The castle's Latin name, Castrum Crepacordis, survives in the dialect of Celle di San Vito, where Crepacore still names a district about 600 m east-northeast of the casale and roughly 1 km from the castle site, although the name has vanished from Faeto's toponymy. The site lies on Monte Castiglione, literally "great castle".
