 The cloister of the church stores up a marble replica of the Standards of the Aragon dynasty.After the earthquake of the 1730, the columns of the cloister were secured, with the addition of tuff blocks to the original structure.Even though the church and the cloister weren't built until 1492, the project of a church devoted to the Virgin Mary dates back to 1460, when Ferdinand I of Naples claimed that in case of victory over the Capetian House of Anjou, at the time set in Arienzo, he would have erect a church.
