Massive research has been done on the architecture, specially in connection with dry and hot climates of the world. In addition to specific attraction and beauty of this architecture, it is in keeping with the climatic-cultural needs and life-style of the people. A clear example of this architecture is Fahadan Bayuzdaran locality. Usually in each locality there is a bath, a small and roofed market-place (Bazaar), and underground water reservoir, a mosque, a place where the martyrdom of Imam Hossein is mourned for (a theater of passion-plays), dregs, small workshops, and a brook. These features revealed the activities and life style of the residents of each quarter or locality. For example most of the coppersmiths settled down in Posht-e-Baq quarter and bricklayers (builders) used to live in Tal quarter and Khorram Shah quarters etc… Among other important localities of Yazd are: Sar Jam'h, Yaqoobi, Sar-e-do Rah, Bajevardi, Mir Qotb, Meidan Shah, Chahar Manar , Do Menar and Shesh Badgir Quarters.
