From TrakyaGezi's site I quote (Google-translated): "Siti Shah is the daughter of Sultan Dulgadiroğlu Süleyman Bey. She was the wife of Fatih Sultan Mehmet Han. It is located on Talat Paşa Boulevard in Sevindik Fakif District. Part of the area where the mosque is built is the palace area. The revenues of the villages of Keşan and its vicinity have been donated for the building, which dates back to 1482.
Rubble stone and brick material were used in the upper parts of the building, mainly of smooth cut stone. Although it is thought that Siti Sultan Şah was buried in his treasury, no tombstone was found.
The entrance to the graveyard is through a portal located on the north facade and positioned between two window openings. Five window openings in 3 rows on the other facades bring light to the mosque.
Its minaret is not original and was built after it collapsed after the 1962 earthquake. The hand-carved ornaments on the mihrab are accompanied by plaster and tile ornaments in various places. The marble pulpit is not original, it was added later."
