Seydi Bey had the mosque built in 1558; the inscription date is Muharram 966.
In 1590, Seydi Bey had a large fountain built in front of the mosque; the inscription text belongs to Seydi Bey.
There are interventions on the mosque façade from the post-Tanzimat period; the large and round-arched window arrangement and the “fil gözü” window show this layer.
The Fatih fire dated 31 May 1918 severely damaged the mosque; the structure remained abandoned.
In the mid-20th century, the structure came to the point of collapse; the plot was used as a parking lot in the following years.
The present mosque was rebuilt in 2016.
Prominent Features:
The structure is also known as “Seyyid Bey Mosque.”
The mosque displays a wall technique defined by rubble-stone alternating masonry walls and brick courses at certain levels.
The upper covering is described as a tile-covered wooden roof arrangement characteristic of neighborhood masjids.
The minaret has a thick-bodied composition; cut stone stands out at the base, and a brick masonry arrangement in the upper sections.
The structure is among the rare neighborhood mosques connected to the infrastructure history of Istanbul through a patron profile directly associated with the Süleymaniye water system.
