An early church at the site was associated with the Patarines, and demolished by the followers of St Peter Martyr.
Under the patronage of Donna Nera Manieri and the Corsini family, a church at the site was founded in the mid-14th century and dedicated to St Catherine delle Ruote.
In 1353, it was joined to an adjacent monastery of Santa Caterina a Monte, and dedicated to San Cajo (Saint and Pope Caius).
The 14th-century funeral monuments of the Corsini family, including Bartolommeo and Filippo, were moved to a chapel in the cloister of the church of Santo Spirito.
