Made of wood in the first half of the fourteenth century, it represents the figure of Christ with deep suffering, with half-open eyes and mouth and accentuated muscular tension, according to the iconography of the 'Christus Patiens'. The miraculous Crucifix is still found in the choir, behind the high altar of the Church of St. Peter the Apostle.

On August 18, 1399, during incessant fighting between fellow villagers, a desperate woman took refuge in the church to pray and, kneeling before the Crucifix, she saw 'fresh blood dripping' from his face, side, hands and feet. She cried out, miracle! Struck and shaken, she ran out to call the fighting people, who, hearing of the miracle, calmed down and put an end to the hostilities.

Thus a true veneration of the Crucifix was born which attracted, even in the centuries to come, religious people from all over the area and which also gave the church the name of Sanctuary of the Holy Crucifix.

In the eighteenth century another miraculous event helped to strengthen the faith in this sacred image. Between 4 and 5 May 1799 a revolt broke out against the French troops passing through who on the night of the 5th sacked the town threatening to set it on fire. The averted danger was attributed to the Crucifix and in addition to 18 August, 5 May also became a day dedicated to remembrance, with the holding of religious and civil celebrations.

Initially it was intended to be an oratory annexed to and used by the hospital of the same name which welcomed pilgrims and merchants who passed through on the nearby Via Cassia-Clodia.

Over time it was enlarged and transformed, the interior was completely redone in Baroque style.

The simple stone ashlar façade is all that remains of the original fourteenth-century construction.

The bell tower next to the church was built recently, rebuilt in 1903 to replace the previous one which was in a very poor state of repair.

Inside is the Crucifix 'of miracles' and it is for this reason that the church takes its name of Church of Miracles.
