Jahrom is a city in and the capital of Jahrom County, Fars Province, Iran. At the 2011 census, its population was 114,208, in 25,946 families.
Sang shekanan or Sangeshkan or Sang Shekan cave which is located in the south of Jahrom and near the Alborz Mountain, is one of the rarest feat in the history of ancient Iran.
this cave was made by stonecutters in the middle of the mountain and this cave attracts the observers because of its beauty. Stonecutters made this cave not just for aesthetics or for fun but they did this for selling the stones and rocks to earn some money.
They inadvertently created one of the world's largest handmade caves, and everyone has a duty to protect this ancient heritage. This cave is nearly 300 meters long and 150 meters wide and a height of 5 / 3 to 4 meters.
