The Sienese War
The only precise information that we have about the life of the Monastery, comes from the 1500s and are detailed by the caretaker-priest Domenico Gabrielli who tells about the violence with which the undisciplined soldiers treated the convent and the church during the Sienese War.
The poor brother tells that in 1555, the soldiers "wrecked the cantina and upturned the wine, rampaging, burning clothing as well as the timbers", and he also informs us that following this they "remained without utensils and furniture but recommenced bit by bit, with the diligence of the brothers and the compassion of their benefactors, to recover".
