In the place where the church is located nowadays, there was an oratory entitled to Saint Michael Archangel. Close to itthe remains of the supposed original parochial building have been unearthed; according to the tradition,it was dedicated to Saint Biagio; it is attestedby the Pope Decima where this place is mentioned. By the year one thousand the church already belonged to the Bishop of Florence.
Subsequently the patronage moved from the Pulci family to the Soldi family, to the florentine sisters of Sant' Orsola and to the Carnesecchi; finally, in 1693, it became the property of the Bardi family from Vernio.

The church received the title of priory in 1712. In 1943 the building was restored.The building shows a sober external structure, on the façade we can see stone jambs framing the rectangular doorway.

In the left chapel of the transept, we notice a painting representing the Madonna with the Child, Saints, devout people and
Mysteries of the Rosary. Behind Saint John Baptist and Saint Caterina of Alexandria, we can make out the clients portrait, they are turning towards the direction of the observer.
