[5]Prodigies of nature: the colours of rainwater in the Grotta dei Cordari

One of the most curious features of the Grotta dei Cordari is the unique effect created by rainwater, which penetrates from the vault through infiltrations and covers the ground, forming a thin lake of still and transparent water.
Thanks to its particular chemical composition, sometimes the rainwater takes on pastel colours tending towards pink and green, with a thousand different shades.
The colours are reflected onto the rock faces and create spectacular plays of light, which make this place magical and evocative.
