Khewra in Jhelum District is the location of the world's second largest salt mines. They were known as Mayo Salt Mines.
History
According to local tradition, the mines were discovered by Alexander the Great's horse while the army waited to fight Raja Porus.[1] They have been mined ever since.
In 1872, a new method of mining was introduced by Dr. Warth, a mining engineer. This method, known as "Pillar and Chamber" has been used ever since.[2]
