This is a complex consisting of a mosque, a graveyard and a mausoleum. The latter is by Sinan, I show it on some pictures. The original mosque was built by Sinan also in 1548,, but has been destroyed several times, and hence the current one is a version by Sultan Abdülhamid II and Şayeste Hanım (third wife of Abdülmecit) in 1858. A çakırbaşı is a person, responsible for the breeding of goshawks, to be used for the (pleasure) hunt by the Sultan. The man was sent to Iran as an ambassador, and later, in 1562, married Şah Sultan, daughter of Sultan Selim II. He later served as a governor-general of Rumelia. Later, in 1573, he died in Kahraman. The mausoleum is not that of the founder, but seems to be for Hacı Ahmet Paşa. As a result sometimes the mosque is wrongly named after the latter.
