This shows that a new local type of mosque was created and developed in the centre of Azerbaijan in the 12th century.

According to V. A. Engelguard:[2] "This Turkish mosque is a great construction with arches made of ashlar and there are many ornaments in its interior.

N. Khanikov, a scientist of Oriental Studies[clarification needed] saw this arch in the 19th century and from a ligature located on its door read that "It was ordered to construct the mosque in 1187, by amir Nureddin – leader of the cavalry and tax collector of the Atabeys’ state of Azerbaijan".

This monument of Nakhchivan which has one of the first arches in such a shape is evidence of the highest level achieved by the Azerbaijani religious architecture of the mid-11th and 12th centuries.

Such a composition of the arch became the main architectural method in a lot of Islamic countries in the next centuries.
