New Julfa is an area located in south of Zayanderud (life giving) River in Isfahan City; Central Iran. At first, it seems like any other areas in Iranian cities but a meticulous eye can find numerous differences. The domes and campaniles of thirteen Armenian Apostolic churches with their eclectic and unique combinations are visible for walkers and they form the visual difference. One can hear people speaking in a different language (Armenian) and the sound of the bells and playing musical instruments from music schools are audible everywhere and this is a different urban sound in cities of Islamic Iran. Even the smell is different. The smell of coffee and gata (Armenian sweet bread) is present in the streets. There are combinations of Islamic and Christian culture in every corner of this area but the most valuable one is hidden in the architecture of the churches. In this essay, I will try to study these delicate and exclusive combinations which are rooted both in the cultural and regional (Old Julfa) differences.
