This mosque has been restored, some years earlier I saw the work in progress. Shah Sultan Mosque is a mosque on Silahtar Ağa street, in the central neighbourhood of Eyüpsultan district of Istanbul. This mosque and its surroundings were the Sünbüli lodge. In 1533, Shah Sultan, daughter of Yavuz Sultan Selim, had it built by Mimar Sinan. Sheikh Merkezzade Ahmet Efendi lies buried in the tomb of the mosque. It has a rectangular plan, stone-brick mixed walls and a hipped roof. The narthex has wooden columns. The prayer room is entered through a single door, opposite the qibla is the mahfili.
