The mosque was damaged by severe earthquakes in the centuries following the conquest, and was completely destroyed in an earthquake in the 18th century, leaving only its minaret standing.
In the 19th century, an irregular neighborhood formed inside the Fortress, and the ruins of the mosque remained among the local buildings.
While Rumeli Fortress was being repaired during the 1953-1958 restoration works, the mosque was neglected and the mosque area was converted into a concert area.
With the initiative of Istanbul Metropolitan Municipality between 2009-2015, the masjid restoration project was approved by the Conservation Area Board. The restoration work, which started in 2014, was completed at the end of 2015 and the mosque was opened for worship.

As the first mosque in Istanbul, it was built on an old cistern in Rumeli Hisarı.
This structure in Rumeli Fortress is also known as Ebu’l-Feth Mosque, Hisar Mosque, Kale Masjid and Boğazkesen Fetih Mosque.
The mosque, built on a cistern, was rebuilt with restoration, remaining true to its original design.
The building, which was neglected for many years, was reopened for worship after the restoration in 2015 and continues to serve.
