Miracle of Florence

Florence, Italy

Blood Type: Not formally testedCoagulated blood (transformed from wine), later found fresh

The Miracle

A priest who had forgotten to clean the chalice after Mass found the remaining consecrated wine had transformed into blood, which then coagulated into visible clots. The blood was preserved and a second miracle occurred in 1595 when the blood was found to be still fresh after 365 years.

Scientific Findings

The blood has been preserved for nearly 800 years. The 1595 examination found the blood to be still fresh after 365 years, which is considered scientifically inexplicable. The double miracle — the initial transformation and the subsequent preservation — provides two distinct phenomena for investigation.

My visit to Miracle of Florence

My visit to the Miracle of Florence miracle site in Florence was part of a larger pilgrimage through Italy. Of all the places I visited, this one left the deepest impression. The evidence is right there, preserved for anyone willing to look.

My visit to Miracle of Florence

The Eucharistic miracle of Miracle of Florence in Florence is one of those things you have to see in person to fully appreciate. Photos do not capture the feeling of standing before something that science cannot explain. I prayed the rosary there and felt deeply grateful.
