Zeynep Sultan  Zeynep Sultan (; 1715 – 25 March 1774) was an Ottoman princess, the daughter of Sultan Ahmed III. Zeynep Sultan was born in 1715 in the Topkapı Palace. Her father was Sultan Ahmed III. In 1728, Zeynep Sultan married (Küçük) Sinek Mustafa Pasha, the nephew of the grand vezir Nevşehirli Damat Ibrahim Pasha, and the second head of the royal stables at the time. The wedding ceremony took place at the Topkapı Palace. On 8 December Zeynep's trousseau was sent to her palace known as "Kıbleli Palace" and the next day the wedding procession took place. After the death of Mustafa Pasha in 1764, Zeynep Sultan in 1765 married Melek Mehmed Pasha, who had previously served as the grand admiral of the Ottoman fleet, during the reign of her half-brother Mustafa III. Melek Mehmed Pasha served as the Admiral of the Fleet for two times and was made grand vizier in 1792. In 1769, Zeynep Sultan endowed a mosque at Eminönü known as "Ruh-i Sultaniye Mosque". A school and a fountain build near the mosque is also part of the foundation. Today it is called Zeynep Sultan Mosque. The complex buildings, located on a sloping and narrow land opposite Gülhane Park, are located in a garden surrounded by wall of obedience, with two entrances in the east and west directions. The 58th verse of the chapter of Surah Ya-Sin, written in 1769, with celî sulus, was signed with a marble hill on the west side of the Sıbyan school, signed with Duâcızâde. The slope of the complex and the height difference affected the floor views of the mosque, the median school and the madrasah, and the basement floor openings could not be located on the west side. Zeynep Sultan died on 25 March 1774 and was buried in her own mosque located at Eminönü.
