One of the earliest settlements of the ancient people in Iranian plateau has been in Kashan, Isfahan province. This has been made known to us by discovering Sialk Historical Mound inside the present city of Kashan. In other words, construction and architecture aren’t new concepts to the dwellers of this city. The historical houses of Kashan I want to introduce are some 18th and 19th century buildings recently restored for the curious visitors who appreciate the subtle cultural points in the construction of living structures of Iran.
