In ancient Rome, part of the soldiers' pay was paid in salt.
From this point of view, we could say that salt is an ancient form of coin.
If you pass the town of Margherita di Savoia (Puglia Region) you can find the biggest salines in Europe ...
... that are also recognized as a National Nature Reserve.
Those salt mountains are huge man-made heaps, waiting for the material to be shipped to Italy and abroad.
There are pathways where it is possible to hike.
The salt in forming can be a spectacular show of colors and sensations, especially at sunrise and sunset.
During summer sunny days you can experiment with a sort of immersion in a bright luminous landscape made of blinding light.
