Above the entrance arch is a tablet with tassels and swags, and inscription reads:
"The Olivetan congregation, with its own and the monastery's resources, built and decorated this temple in this form, during the reign of Paul V Borghese the Roman Pontiff, 1615"
Above this epigraph is a large rectangular window framed by a pair of Ionic columns supporting an entablature and segmental pediment. There is a balustrade in front of the modern stained glass window of the Crucifixion, by János Hajnal.
