The story
As you stand here in the narrow, quiet stretch of Via San Remigio, take a moment to look up. Just near the corner of the building, you will see two stone markers set into the wall, one above the other. They look like simple plaques, but they tell a haunting story of a city defined by the river that both gives it life and occasionally threatens to take it away.
These are the flood markers of Florence. The lower one is weather-worn, its medieval script carved in 1333. The one just above it, clearer and sharper, marks the year 1966.
If you hold your hand up toward them, you will realize just how high they are—over four meters, or nearly fifteen feet, above the ground you are standing on. In this very spot, on two different days separated by six centuries, the Arno River turned this street into a deep, swirling canyon of destruction. The date on both plaques is identical: November 4th.
It is a date that every Florentine knows in their bones. On November 4th, 1333, the river burst its banks with such force that it swept away almost all the city's bridges, leaving only the sturdy foundations of what we now know as the Ponte Vecchio. The water rose so fast that people were trapped in the upper stories of these very houses, watching as their shops and livelihoods were swallowed by the silt.
Fast forward six hundred and thirty-three years to November 4th, 1966. It began with a relentless, heavy rain that many thought would simply pass. But by dawn, the Arno had breached the embankments.
A wall of water, mud, and heating oil roared through these narrow streets at forty miles per hour. As you look at that 1966 marker, imagine the silence that must have fallen over this neighborhood once the roar subsided, leaving only the sound of water lapping against the stone at that incredible height. There is a chilling precision to these markers.
The fact that the water reached almost exactly the same level in two different eras serves as a reminder of the geography of Florence. This area is a natural basin, and when the Arno overflows, the water finds its way back to its ancient paths. But there is also a story of resilience here.
In 1966, thousands of young volunteers from across the world, known as the Mud Angels, descended on these streets to pull priceless manuscripts and Renaissance masterpieces out of the muck. Today, Via San Remigio is a place of peace, filled with the scent of traditional Tuscan cooking from the nearby trattorias. But as you continue your walk, keep those markers in mind.
They are the watermark of a city that has learned to live, build, and dream in the shadow of the river.
