Castello di Pieve del Vescovo, Medieval fortress in Corciano, Italy.

Castello di Pieve del Vescovo is a medieval fortress near Corciano in Umbria, featuring four corner towers and walls arranged in a quadrilateral shape. The structure sits on a hilltop overlooking the Caina Valley.

In 1396, the original church building was converted into a fortress with permission from Perugia. This transformation marked the beginning of its military role in the region.

The name Pieve del Vescovo comes from Cardinal Fulvio della Corgna, bishop of Perugia, who in the 1560s and 1570s had Galeazzo Alessi convert the pieve into a summer residence with gardens. Taddeo Zuccari frescoed several rooms; the Chapel of San Giovanni Battista, the cardinal's coat of arms, the stables and the prisons can be seen.

The castle stands on a hill about one kilometre from Corciano, above the Caina valley; the climb is on foot. Since 1999 the local masonry school has managed the restoration and uses the rooms for cultural activities, so access depends on those events rather than fixed visiting hours.

In 1397, this fortress hosted the wedding celebration of military captain Biordo Michelotti and noblewoman Giovanna Orsini. This grand event shows how important the location was as a venue for significant aristocratic occasions of that era.
