On the road from Isfahan to Yazd there is the town of Meybod.

The town itself is small. In the city you can see the yakhchal (this is an ice storage facility), Ab anbar (a water reservoir) and the pigeon tower. The real treasure is located a little away from the city. This is the majestic mud fortress of Narin. The Narin fortress was built in the fourth millennium BC. Essentially, it is a fortified city. Behind high walls reaching a height of up to 25 meters, there were multi-level rooms (up to five levels). The lowest floors were reserved for the housing of the common people, the middle floors were for commercial purposes, and the upper floors were intended for the nobility. The highest parts of the terrace and the four towers were occupied by the military.
