Following drawings were done in order to better understand the City of Yazd in Iran. Because of generations of adaptations to its desert surroundings, Yazd has a unique architecture. It is nicknamed the "City of Windcatchers"  from its many examples. It is also very well known for its ab-anbars (cisterns), qanats (underground channels) and yakhchals (coolers).  Yazd is also known as City of Bicycles, because of its old history of bike riders in Iran.
