According to ISNA, the people of Yazd, deprived of natural resources such as water and fertile land, inevitably had to get water for the first thing they had to do to create a city for living in the desert. For this purpose, they invented the aqueduct or Qanat with creativity, ingenuity, and hard work. That led them to the idea of Adobes.
With this invention, water came to the desert city, and at that time, their only possession was water and soil. Desert cities lacked organic construction materials. With the combination of the water and soil, the people Yazd built all the buildings, fortifications, husseiniyahs, military structures with adobes.
Water structures such as water reservoirs and mills also have adobe as their material. Over the years, they have learned how to use the elements of their climate, which are water, soil, and sun.
The first structures built in the city of Yazd date back to pre-Islamic times, and they made most of the buildings out of clay and adobes. That is, in the form of stratification, and then evolve.
Human knowledge reaches a point where it can use molds that overlap. The size of the raw bricks used in the early periods was large. And they thought that with large adobes they could raise buildings faster. Over time, the dimensions and type of clay gradually changed.
One of the most significant steps in preparing clay is the composition of water and soil and kneading. The clay is usually beaten outdoors to dry in the sun. The largest volume of clay is for inner buildings such as Narin Qaleh Meybod, Yazd Tower and Fortress, and Aberandabad Castle. Bricks used to be used in the restoration of historical buildings, but now we have returned to the era of using clay. Clay and adobes production workshops have increased rapidly in parts of Yazd province, and clay production in the province’s cultural heritage restoration workshops has reached more than one million bricks per year.
