In 1478 Duchess Giustiniana Orsini (wife of Raimondo Orsini, Duke of Gravina and the vice-king of Naples) moved to Scandriglia where, unfortunately, her first son became seriously ill. The Ducchess was devastated by tragedy and addressed numerous pleas to the Madonna delle Grazie in order to save her son. She promised to build a sanctuary dedicated to the Madonna if the young boy was healed from is terrible sickness. Her prayers were soon fulfilled and the boy miraculously returned to good health. The Duchess, however, forgot her vow and her son again begame ill. Fortunately, and strangely, the boy's health improved, and this time his prents, after a request to Pope Sisto IV, decided to construct the promised sanctuary, appointing the Portuguese Jaoo da Silva e Menezes as director in charge of the work. Joao da Silva was later to become famous as friar Amedeo when he entered the Franciscan Order. The whole structure was completed in 1480 and the miraculous image of the Madonna was trasferred there from the Baronial palace of Nerola. Nel 1566 Pope Pio V abolished the Amadeiti congregation and the monastery, upon request of Cardinal Flavio Orsini, was entrusted tio the reformed Minor Friars of "dell'Osservanza" A magnificent avenue, sided by cypresses planted in the first half of the last century, gives access to the religious building. Once through its walls, two doors placed under a larger arcade lead us to the internal church and monastery. The single nave church has a polygonal apse and a truss roof whilst the three chapels open on to the left hand-side of the hall. The first of these chapels bears a finely finished wooden painting in tempera depicting a "Madonna in trono con bambino tra i ss. Francesco e Antonio" attribued to the fifteenth century School of Umbria and Lazio. On the high altar we can admire the fondly worshipped image of the " Madonna delle Grazie". The whole structure is completed by a large cloister and a refectory whose walls conserve a fine and precious fifteenth century fresco representing the "Crocefissione".
