Castello di Procoio, Medieval castle in Migiana di Monte Tezio, Italy

Castello di Procoio is a medieval castle near Migiana di Monte Tezio outside Perugia, built in stone and brick following traditional military design. Its square plan is defined by two truncated round towers positioned at the corners of the fortification.

The oldest part, the northwest corner, was built in the 12th century to control the road from Perugia to Gubbio. The present square castle was begun in 1455; in 1473 and again in 1480 the community of Migiana asked Perugia for subsidies of 30 florins, and a 1481 document shows it nearly finished but still without a water supply. It remained incomplete, and the corner bondings for two planned towers were never filled.

The castle's chapel is dedicated to Sant'Eurasia, a saint invoked as protector of crops and the countryside. The building is also known as Castello di Santa Eurasia, the name given to it by its current owner Evgeny Lebedev, replacing the older name Castello di Procopio.

The castle stands above the village of Migiana di Monte Tezio, north of Perugia, and is reached by the road climbing from the village. The building is private and not open to visitors, so the structure is seen from outside. The east side preserves traces of the original entrance, whose door was topped by corbels for a defensive apparatus.

The oldest section, known as the original 12th-century core, sits in the northwest corner and reveals the structure's origins. This location was chosen to keep watch over the trade route connecting Perugia and Gubbio and maintain regional control.
