Borgo di Castiglion Fosco con torre cilindrica

Castiglion Fosco is a fortified hill village in the municipality of Piegaro. Its cylindrical tower rises above houses and surviving castle fabric overlooking the Nestore valley.

Why it matters

The settlement preserves the relationship between domestic buildings and medieval defence. Its hilltop position placed it within the network of castles governing the surrounding countryside.

What to notice

The round tower, dated to the fifteenth century, forms the village’s most recognisable feature. Wall traces and the remains of the castle are incorporated into the inhabited settlement. The church of Santa Croce preserves paintings and a wooden cross from later periods of the community’s religious life.

Context and history

Tradition connects the village’s name with a grant to a man called Fosco during the Ottonian period. Its later history belongs to the Perugian countryside and the neighbouring fortified settlements. The fifteenth-century tower represents a later defensive phase, rather than evidence that all the visible fabric dates to the village’s earliest origins.
