SIDE BY SIDE/Arno, from source to mouth
Until November 30
Palazzo Medici Riccardi, via Cavour 4, Florence
Take an illuminating ride down the river: Palazzo Medici Riccardi will display photographs of points along the Arno, highlighting what certain areas looked like in 1966 compared to their current appearances. The images illustrate what’s been done to combat hydrogeological instability in the five decades since the flood.
