Mimar Sinan (allegedly, but not mentioned in official sources)
- Changes after its construction
In the 19th century, the wooden porches were removed and replaced with simpler porches.
These porches were also removed in the 1940s and 1950s.
Within the scope of the restoration works carried out by Fatih Municipality in 1995, the Ivaz Efendi Fountain in the front courtyard of the mosque was restored and revived again.
In 1998, the Sakal-ı Şerif (“The Blessed Beard”, a relic of the Prophet Muhammad), who was hidden in the mosque, disappeared, and despite searches, has not been found yet.
In the 2000s, various arrangement works were carried out in the courtyard and the graveyard, and the surroundings of the mosque were renewed.
- Prominent features
It is also known as Eğrikapı Mosque.
It has a hexagonal foundation, a single main dome and five half domes and is an original example of classical Ottoman architecture.
At the back of the mosque are the ruins of the Anemas Dungeons from the Byzantine period.
The mihrab is decorated with the finest Iznik tiles of the 16th century and increases the artistic value of the mosque.
Numerous window details that illuminate the interior with natural light offer an aesthetic reminiscent of the Zal Mahmud Pasha Mosque in Eyüp.
The grave of Kazasker İvaz Effendi is located in the graveyard in front of the mosque and is marked with large cylindrical stones.
