TEHRAN -- A team of experts is preparing a study plan for the Tarikhaneh Mosque of Damghan in northern Semnan Province in order to add to the scant information on the monument, which is believed to be Iran’s first mosque.

“When the team completes the plan, the most comprehensive historical, architectural, and archaeological study plan on the mosque will begin,” team director Zarrintaj Sheibani told the Persian service of CHN on Tuesday.

“Experts are in the final stage of the work. Research on the Tarikhaneh Mosque is important from various angles, thus the work is very complicated,” she added.

The team got the idea to draft the plan after a section of the mosque was discovered during a restoration project on its exterior.

“Since study of the mosque would be almost impossible without taking into consideration the architectural and urban structure of Damghan, we had to acquire a large number of documents and records on the city, which, fortunately, we obtained,” Sheibani said.

“It is very important for the study whether Damghan is a pre-Islamic city or not, so we have to research the history of the city in the first step,” she explained.

No comprehensive study has been carried out on the mosque and the city since the topographic and archaeological studies of French architect Andre Godard in the 1930s, lamented Sheibani, adding that she hopes the study plan provides the comprehensive information on the mosque and the city which has been lacking.
