Mir Emad Mosque is located on the south side of Faizieh Square, or the former Sang Square, next to the Grand Bazaar of Kashan. The original building belonged to the Seljuk period, which was destroyed after the Mongol invasion, and then rebuilt by Khajeh Emad al-Din.

The building of this mosque belongs to the sixth and seventh centuries AH and includes Jolkhan, two entrances with historical inscriptions, Hashti, Sangab, two-story courtyard, two rows, several naves, brick dome, exquisite mosaic tile pulpit and historical water reservoir

In front of the mosque, eleven historical orders and decrees have been placed on silver stone and installed on the wall. The contents of these royal decrees represent the political and social situation of that time. The entrance of the mosque has a bed of train tracks and paintings with water and paint

This is the entrance to two inscriptions dated 868 and 869, one of which is the name of Jahanshah Qaraquyunlu and his wife Hareem al-Aliabigam, and the other is a decree from two of them. This entrance and its decorations have been repaired several times and the last date of its repairs is 1243 AH, which was done by the order of the ruler of Kashan (Ismail Khan) at that time

According to sources, Khajeh Emad al-Din, during the reign of Jahanshah, after returning from Mecca, built this mosque in front of Feyz Square in Kashan. The mosque’s endowments include other buildings around the square, including a bathhouse, a monastery and a mechanical clock. Opposite the mosque was a school and a house, and to the east was a caravanserai. In 897, Qutbuddin bin Shams al-Din Firuzabadi Meybod Yazd dedicated a mirror cup to the mosque, which was installed in the entrance hall of the mosque.

By order of Shah Abbas I, on the west side of the mosque, buildings were built for the residence and reception of the clients and residents of this mosque, of which there is no trace today except the large water reservoir and a stone inscription dated 1033.
