The church has a hut-shaped façade; the entrance is preceded by a short portico with three round arcades supported by brickwork pillars.
The nave ends with a deep apse with a modern stone altar, a Baroque wooden tabernacle and the choir.
According to Franciscan sources, a miracle in which Saint Francis' heard an exhortation from Christ occurred in 1205 in this church:[1] One day out in the countryside to meditate.
Finding himself near San Damiano, which threatened ruin, old as it was, driven by the impulse of the Holy Spirit, he entered to pray.
On hearing that voice, Francis remained astonished and trembling, being in the church alone and, perceiving in his heart the power of divine language, felt kidnapped of his senses.
