The underground city
the underground city of Ouyi (Noushabad) in the northern Kashan - Isfahan province - is considered one of the masterpieces of ancient architecture. as Noushabad city is located in the region of central desert of Iran, its weather is quite harsh. during the day Noushabad has a very hot temperature and during the nights it gets pretty cold. The reason why this city is called Noushabad (meaning the city of cold tasty water) is because in the ancient times one of the Sassanian kings who were passing through this area stopped here to drink water from a well and he found this water extremely clear and cold. Therefore he ordered to build a city around this well and name it Anoushabad which eventually turned into Noushabad. A few months ago in the Civiltect website we introduced another underground city which was located in the south of Australia. It was explained that the main reason for this underground city being built was to escape from the daytime high temperature of the region. However the main reason underground city of Noushabad was carved stemmed from the fact that in the past this region was quite insecure and by forming an underground chain of passages beneath the entire city, the inhabitants would shelter there in the time of being attacked. And also through these passages they could reach any spot of the city without being seen. The depth of this underground city varies from 4 to 18 meters and the different spaces formed by carving the rocks seem a little scary! To reach the underground city there were several different openings. some of these openings were located inside the houses of people and some others were located in important gathering places such as the main fort just outside the city. People could live in the underground passages and room for several days without the need of going outside. There are three levels in this underground city and these levels were cleverly planned in a way that going to the different levels required moving from down to up. This made it easier for the people sheltering in the underground city to prevent enemies from getting to the upper levels. Another interesting feature of their architecture was the curvy passages that made it possible for the inhabitants to ambush enemies. Furthermore there were several other tricks that were used to resist against the enemies, for instance digging deep holes in the middle of the rooms and covering it with rotating stones that would fall down if anyone stepped on them. Noushabad is located about 5 kilometers north of Kashan.
