In brief
The historic Yazd shows how desert habitation depends on a combination of architecture and water supply.
Useful to know
The historical Yazd in Iran is an example of land architecture associated with the use of limited resources in a desert. UNESCO lists the kanats - a system for bringing in underground water - as part of the urban heritage. [1]
The preserved environment includes dwellings, bazaars, baths and various religious buildings. It is a living urban ensemble, not a monument that can only be explained by height or style. [1]
When considering a general plan, look for the relations between neighborhoods, public functions and water supply. Invisible underground infrastructure should not be missed just because it is not present on the tourist shot.
Do not automatically conclude that each building of land has the same construction or the same behavior in climatic conditions. Here confirmed is the relationship between the traditional urban environment and a specific water supply system. More detailed claims about a separate house require its own study.
