Meybod

bout 52km north of Yazd, Meybod is a sprawling mud-brick town that is at least 1800 years old. Of most interest is the crumbling Narin castle in the centre of town. This dates from Sassannian times and may well be the oldest existing mud-brick structure in Iran. Climb to the top for fantastic views across Meybod’s rooftops and into the desert.

There are also two sites of minor interest near each other in the west of town: a 300-year-old post house and a huge caravanserai where a few locals operate handicraft shops. In front of the caravanserai is a handsome ab anbar and opposite is a huge, conical-roofed Safavid-era ice house (yakh dan).
