When taking into special consideration, the history of the architecture of Iran is such a comprehensive topic on which a certain restriction must be made. There are many examples to be found within the present-day national borders as well as within the timespan from the 6th century B.C. until 1979. The architectural examples presented here have always been contingent on different topographic and climatic conditions in addition to diverse cultural influences. Rock architecture and mosques – bazaars, baths and palaces, as well as modern public buildings and housing-are among the relevant topics this book covers. Wolfram Kleiss characterizes in this volume the architectural history of Iran from the 4th millennium BC to the present day.
