Roknolmolk Mosque (Persian: مسجد رکن الملک) formerly known as the Aksa Mosque is a historical mosque in Isfahan. This mosque was built in Qajar era and is next to Takht-e Foulad cemetery.[1] It was named after and founded in 1901 by Mirza Soleyman Khan Shirazi, who is known as Roknolmolk.[2]
The mosque was founded in 1901 by Roknolmolk but ultimately completed in 1907. In 1914, seven years later, Roknolmolk was buried in an empty room of the mosque. An inscription on the mosque dates the completion of a final renovation to 1958.
The mosque building is made out of bricks. This mosque has two doors, and an entrance gate decorated with flower designs. The arch of the main door is about 9 metres wide. There are steps for the muezzin to climb onto the roof of the prayer hall, as the mosque has no minarets.
Behind the entrance of the mosque, there is a secluded space which leads to a room that is the mausoleum for the Shi'ite clerics who belonged to the Kalbasi family. On the south side of the courtyard, there is a door that is the entrance to a water fountain.
After passing through the main hall, a corridor connects the small court to the bigger court of the mosque. In the same hallway, there is a doorway on the left, which leads to a small room where the tomb of Roknolmolk himself and his wife are located. A wooden zarih encloses the two graves together.
On the west of the mosque courtyard is a musalla which is for the winter season.
