The Juyushi Mosque is located on the hill of Mokattam, where below it is a panoramic view of Cairo. The mosque’s importance comes from its minaret which is the oldest surviving Fatimid minaret in Egypt. It is also the first stone built mosque in Cairo. The Juyushi mosque was built by the vizier Badr Al-Jamali and completed in the reign of Al-Mustansir Billah in 1085.

The Juyushi mosque has an area of 270 m² and is divided by an axis into two symmetrical halves, except for a well that is present in the north-eastern corner of the mosque, which was added later after the mosque’s construction. The mosque also has a small courtyard. The main entrance to the mosque lies at the base of the minaret and leads to a vaulted passage, which has two rooms on its right and left sides. There’s also another entrance from the courtyard to the mosque. Inside the mosque, there are several vaulted ceilings which are supported by pillars. There’s also the mihrab inside the mosque, which is beautifully decorated with decorations similar to those of the mihrab in Al-Azhar Mosque. The mosque also has a lot of inscriptions, mostly Quranic verses, which can be found at the entrance, at the dome and at the mihrab. This mosque was probably used by Sufis as a monastery during the Ottoman times.
