The enormous and ancient Salt Mines of Khewra, said to be found by horse of Alexander the Great

It is perhaps due to the importance of salt that one of the biggest salt mines in the world is associated with one of the greatest conquerors of the ancient world.

Cheap and easily available, salt is one of the many things that we take for granted today. Yet, for many societies of the past, salt was a valuable commodity as it was not commonly available to everyone. By using the precious salt to preserve food, people in the past had a higher chance of surviving through the winter months, and were able to travel long distances using salted foodstuff as sustenance.
