S. Apollinare rises on top of the hill, like many medieval castles built to defend the southern part access to the city of Perugia, along the Byzantine wall.
This medieval castle, with its imposing embattle stronghold and its cloisters has kept its feudal structure.

S. Apollinare was named after Ravenna’s archibishop and dates back to the Xth century.
In fact, the first date mentioned in historical documents is 1010, year in which the castle was partly burnt by the imperial army.

Subsequently, in 1030, Ugone, son of Alberigo, together with his wife Deodata, gave it to the Abbey of Farfa.

In 1060, the Abbot of Farfa gave the castle in emphyteusis to Bonizone, Abbot of the Monastery of S. Pietro, for an annual fee of twelve Pavian “soldos”.

Subsequently, in the XIIIth century, the castle of S.Apollinare became the residence of the Graziani family until 1700, as the Abbot of S. Pietro gave it to them in return for alliance and military protection.
