 Its documented existence can be traced back to the year 986.Either founded or endowed by the Bishop of Fiesole, the church was originally orientated differently to the existing oratory, and the building essentially caused the once sizeable piazza in which it was built to be bisected.This operation formed what is now known as the Piazza San Martino, which opens out in front of the Buonomini’s oratory and the Piazza del Cimatore.
