The ice house is an interesting concept. And useful for the hot desert. Water is channelled here via qanats to freeze in winter for use in summer. Made of adobe, the icehouse is like the predecessor of the modern day water cooler found in most places we went to Iran. Just much larger with no electricity required. This icehouse in Meybod is said to be from the Safavid era.
Needless to say, it was very cool inside here. I didn’t want to leave.
