The Roknolmolk Mosque (Persian: مسجد رکن الملک), formerly known as the Aksa Mosque, is a Twelver Shi'ite mosque, located in Isfahan, Iran. Completed in the early part of the 20th century, the mosque was built in Qajar era and is adjacent to the Takht-e Foulad cemetery.^[1] It was founded in 1901 and built by and named after Mirza Soleyman Khan Shirazi, who was known as Roknolmolk.^[2]

The mosque was founded in 1901 by Roknolmolk and completed in 1907.^[2][1] 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.^[1][2]

Made out of bricks, the mosque has two doors and an entrance gate decorated with flower designs.^[2][1] The arch of the main door is approximately 9 metres (30 ft) wide. There are steps for the muezzin to climb onto the roof of the prayer hall, as the mosque has no minarets.^[2][1]

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.^[2][1] On the south side of the courtyard, there is a door that is the entrance to a water fountain.^[2][1]

After passing through the main hall, a corridor connects the small court to the bigger court of the mosque.^[2][1] 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.^[2][1]

On the west of the mosque courtyard is a musalla which is for the winter season.^[2][1]
