Making ice in the desert? The irony is in the sentence itself, as most people can only fathom making ice by using their freezers, in a practical and modern manner. However, people had figured out how to make ice in the desert over a millennia ago. This practice requires an ingenious structure called a yakhchāl, and was used as far back as 400 BC.

Believe it or not, it’s actually stated in the Bible that people could make ice in the desert at a time long before electricity and fridges. This practice seems baffling for modern society, but it was actually quite simple and practical – and most often used in Persia. The creation of yakhchāls (a Persian word – yakh meaning “ice” and chāl meaning “pit”), a structure which worked as a cooler, allowed the freezing of water to take place.

Yakhchāl

Yakhchāls were large above ground structures built with heat-insulating materials which served as coolers during the hotter months of the year. The structure had a deep hole in the center of it, which lead to an underground storage space. Yakhchāls were often used to store ice which naturally formed during winter, as well as storing food. However, these structures were also able to freeze water – even in the desert!
