Santi Apostoli is a deconsecrated former Roman Catholic church located on Via Lattanzi in Orvieto, Umbria, central Italy.
[1] It was linked to the parish of San Lorenzo de' Arari, patronized by local nobility.
This structure was likely in dire need of refurbishment when in 1614, part of the endowment of a wealthy merchant active in Venice, Muzio Cappelleti of Allerona, was designated to establish a seminary for the indigent called Collegio Capelletti.
In 1621, cardinal and bishop Pier Paolo Crescenzi granted the adjacent Palazzo Monaldeschi to house the school.
The structure still contains an altarpiece painted by Vincenzo Pasqualoni depicts the Immaculate Conception with the Saints Apostles Phillip and James.
