Palazzo De Petris-Fraggiani (Castello)

The castle is the focal point of Castiglione a Casauria’s planned medieval town. Known since the 1700s as Palazzo De Petris-Fraggiani, the building closes the fortified village's triangular plan at its sharpest angle. Seen from the public streets it still commands the ridge above the Pescara, and it explains the borgo better than any plaque could.

Why it matters

The park authority's official village page and the regional tourism portal agree on the essentials: the castello of Castiglione a Casauria is triangular, and from the eighteenth century it has carried the name Palazzo De Petris-Fraggiani. That shape is not an eccentricity. Castiglione is a planned borgo: Adami I — abbot of San Clemente a Casauria — laid it out around 980, and by 987 the settlement appears in the documents, its walls, houses and castle designed from the start as a single defensive figure on the crinale above the river. The castle supplies the point of that figure — the punta triangolare, in the park's wording — where the enclosure narrows to its tip. Its importance lies less in its interiors than in its place at the apex of the borgo’s defensive geometry.

What to notice

The palazzo’s roofline dominates the houses gathered beneath it, a visible statement of seigneurial power within a community of abbey tenants and craftsmen. Where the streets converge toward the punta, the castle walls and village fabric appear as parts of a single project. The triangular plan sits against the valley, with the ridge behind and the Pescara corridor below. Stone portals and masons’ balconies in the borgo reflect the work of local scalpellini.

Context and history

The castle's story is inseparable from the institution that founded the village. The abbey of San Clemente a Casauria, established by Emperor Louis II in 871 beside the old Via Claudio-Valeria, dominated the middle Pescara valley, and its abbots built this fortified settlement at the end of the tenth century to hold their territory. The settlement appears in documents by 987. For centuries the enclosure served the abbey's administration and defence; later the triangle's apex building passed into lay noble hands, and by the eighteenth century the name Palazzo De Petris-Fraggiani — recording the family that then held it — had attached to the castle, the designation both official sources still use. The structure thus spans the full arc of the village's history from abbey foundation to baronal residence, even though its older military face is what the urban plan preserves most clearly.
