The Jām'eh mosque

The Jām'eh mosque (congregational, Friday) is located in the city of Semnān (region of the same name). The construction of this ancient and important mosque is attributed to the centuries of the first Islam. Except for the ghaznavide-Seljuk minaret, it contains traces of the Ilkhanid, Timurid and even qajaro period repairs.

Considering the research of the excavations carried out, this mosque was probably built on the ruins of an older building. The different parts of it are as follows:

-Shabestan winter (underground), the oldest prayer hall of this mosque located in the southern wing built entirely in style Khorasani with narrow arcs.

-Shabestan Abā Harab Bakhtiār located in the eastern wing; from an architectural point of view the columns are very similar to those of the Tarikhāneh Mosque of Dāmghān and thanks to a small vestibule with a domed vault and ornamental motifs it connects to the external bazaar.

-Minareto brick and ancient high over 30 meters located to the north-east of the Shabestan Abā Harat Bakhtiār.

-Iwan brick and tall of the Maghsureh dome with a height of over 21 meters which is located in the west part of the mosque's courtyard. In the three parts of theIwan there is an inscription on tiles that includes the date and the name of the manufacturer. In the lower part of the epigraph there are some large slabs of stone, and on the most important one are the edicts of the Safavid king for the inhabitants of Semnān. On this Iwan there is a Seljuk dome.

-Shabestan southern with numerous circular columns that support its arch. 

-Shabestan northern with 16 circular and thick columns on which arches are held to the south.

The inlaid door in the north corner that connects the mosque to the outside is also located next to it Shabestan.
