Its opening celebrations were held in 1661 after Antonio Raggi had completed the decorations in stucco inside the dome.
The religious building, open to the public, has a Greek cross layout surmounted by a dome coated with layers of lead and with a lantern to illuminate the interior. The façade is developed vertically and structured on two levels: the portal is in the lower part while in the upper part you see a large window and a tympanum bearing the Chigi family’s crest.
Inside the church are paintings by Borgognone and works by Pietro da Cortona: an alterpiece in the main alter illustrating La Crocifissione con Maria (The Crucifixion with Mary); La Maddalena and San Giovanni (Magdalena and St. John). as well as the stuccoworks by Antonio Raggi.
