The Oui complex was constructed under the old structure of Noushabad city and has expanded to the current level of the city. The area of the discovered part of the Nooshabad underground city is about 12000 square meters, which has been expanded on both horizontal and vertical levels due to the connection between the neighborhoods and the protection of people’s lives and property in times of insecurity.
So far, 3 important parts of Noushabad underground city have been discovered and explored; The first complex is about 1000 square meters and the second complex is about 4000 square meters. These two collections have been prepared for tourists to visit. But the third complex, which is bigger than the previous two and includes an area of about 7000 square meters, has not yet been opened to the public.
The soil of this area has high strength and stability, as a result, the structure of the city has been preserved as it has stood for thousands of years, and there are no signs of collapse or major structural changes. Except for the main entrance, the height of all parts of the underground city of Nooshabad is equal to the natural height of a human and between 170 and 180 cm. On the walls in a row and at short intervals, there are places for installing tallow lamps, which were necessary to supply the city’s lighting. In some parts, short platforms for sitting have been created inside the wall, which in some rooms become ledges for placing things.

Air condition of the underground city of Nooshabad

The process of air conditioning of the Nooshabad underground city is through the channels created on the first floor and to the ground level. The related wells of the floors, in addition to the function of passage, have caused air to flow on the lower floors. This practice also applies to aqueduct wells. The shape of these well corridors is in the shape of the letter “L” and this issue causes the difference in air pressure and the arrival of fresh air and oxygen to the basement floors.
Access to these spaces is possible due to entering underground through a well and a narrow and short channel. The issue of defence and shelter of this type of architecture created in the heart of the earth has had a significant impact on how to present its architectural plan; Therefore, regarding the entrance, access to these spaces should not be done easily.
The lighting of these spaces was provided by means of clay burners, and their oil was probably prepared from two historic distilleries in the underground city of Nooshabad. In times of insecurity and taking shelter in the basement, the residents’ drinking water is provided from the aqueducts.
