Windmill (Asbad) is one of the most important kavirian architectural constructions in Iran. This small and apparently plain and simple factory is the significant evidence of ancient Iraniansʹ ability to put art and science together in using native and local feasibilities and possibilities and natural power to satisfying their first need of having food. Khourasan as a vast area in Iran has an old history in crea- tion and production of brilliant architectural constructions before and after adopting Islam by Iranian people, especially during Islamic period. In this area, there are lots of unique incomparable windmills which are more than 1000 years old. These exclusive and exceptional windmills can be found in Nahbandan, Khawf, Nashtifan, Khargard, Barabad and some other areas in Great Khourasan, among all of them only Nashtifanʹs windmills complex is long-lasting and still standing. Actually, even now some parts of this set of buildings are working. Another reason for the significance of this study is that, this local-industrial unique architectural complex is the most matchless and incomparable windmill construction in Iran and the oldest windmill complex with vertical axis in the world. This review gen- erally deals with a broad look at windmill as a local-industrial unique architectural construction and specifically with describing Nashtifanʹs windmills, their architectural structure and organization, their operational procedure and functional process in order for revealing their great concealed and hidden architectural values. The research method is analytical-descriptive. In order to prepare and propose a theoretical framework for obtaining and using information about architectural specifications and characteristics, firstly review of literature will be done on several questions about windmills and their function. In situ investigation and comprehensive assessment and examination of a windmill unit is another important part of this research. The result of this part of the study is preparation of some plots and drawings of a windmill unit which is one of the few and limited working and ongoing units. In these plots and schemes, architectural spaces in a windmill unit are shown. Theses spaces and rooms are "Askhane", the bottom room of windmill and the place of mill stone, and "Parkhane" the top part of windmill and the pace that "charkhbad" (wind round or disk) is located. Two points that are discussed in this paper are especially worthy of notice: first the operation system of windmills from first step of providing wheat to the last one of making flour and stopping the circle of windmill; second is the local construction materials used in Nashtifan Windmills. Some of these local construction materials which have an important and vital role and position in proper and appropriate work of windmills are the wood of some native trees, mud brick, and Kahgel (mix of clay and straw). According to these points, this study is aimed to show the hidden values and capacities of this unknown architectural structure of our cultural heritage so that high-quality and superior conservation can be provided for this worthy and valuable achievement
