With increasing growth and development of cities, we get surprised crossing the city old neighborhoods. Thatch walls and clay houses remind us of simple lifestyle of old people. Azar Street is one of the oldest neighborhoods in Qom that you can see lasting heritages from hundreds years ago by crossing it. At noon, when sun shines over the Labchal Neighborhood, you can hear the sound of Adhan. There is definitely a mosque in this neighborhood. It is said that Jame Mosque in Qom in this neighborhood was built 800 years ago.  It is a mosque that shines like a diamond in the middle of Qom desert. The dome was built before other parts of mosque that returns to Seljuks based on historical writings. The designers and creators of Jame Mosque in Qom have created 2 entrance doors to this mosque that one of them is in the west part and is considered as the main entrance and the other one is in the northern section. Jame Mosque in Qom is affected by Iranian architecture like tiling and Quranic inscriptions which make this mosque look more glorious. The architecture of mosque is another interesting point that can determine the time of the noon Adhan by an indicator which is carved on a stone in northern part of the mosque. The light wells in different parts of building circulate the air and make it cool and fresh besides supplying lights. There is an unbelievable fact about Jame Mosque in Qom that there is no Iron used in this building and it is still firm and strong.  You can visit this monument and other tourist attractions of Qom by Alaedin Travel in your trip to Iran.
