The ancient Gothic windows of the facade were changed with two square openings and the portal was replaced with an eighteenth century entrance. 
On the two sides of the church a double row of bricks shows the original height of the building and, still here, are two beautiful Gothic mullioned blind windows.The apse, now rectangular, was modified. According to the cadastral survey of 1729 was in fact a semi-circular shape. Even the beautiful window which lights inside the church is eighteenth century.
The interior shows more Gothic traces: the eighteenth-nineteenth century restoration work has changed the appearance. Shortly before the abolition of 1860 Father Raffaele Lauro had the last stucco decorations placed on the eighteenth-century altars.
This church, like many other of Corciano, was a place of burial. There are still three tombstones on the floor.
There are many art works created for the monastery, stands out among all the banner by Benedetto Bonfigli, currently preserved in the parish church, and four beautiful Baroque reliquaries.
In this church the four patron saints of the City are venerated: St. Michael the Archangel, St. Sebastian, St. Roch and St. Macarius.
The convent, originally built for twelve monks, is now privately owned. Inside there's a beautiful cloister,  painted with the Stories of St. Augustine, with captions in verse of the late seventeenth century by erudite Costanzo Ricci of Corciano. Unfortunately they are very damaged.
