Zal Mahmud Pasha Mosque

The Zal Mahmud Pasha Mosque () is a 16th-century Ottoman mosque located in the Eyüp district of Istanbul, Turkey. It was designed by the imperial architect Mimar Sinan and completed in 1590.
History.
The building of the mosque was jointly endowed by Shahsultan and her second husband, the Bosnian born vizier, Zal Mahmud Pasha. Both had died in 1577. Shahsultan was one of the daughters of the sultan Selim II and his wife Nurbanu Sultan. After the death of Shahsultan's first husband in 1574 she married Zal Mahmud Pasha who in 1553 under Suleiman I's orders had strangled Şehzade Mustafa, a half-brother of Selim II and Suleiman's eldest son.
The mosque was designed by the imperial architect Mimar Sinan. Building work began in 1577 but was not completed until 1590, two years after Sinan's death.
