The three-lobed frame above a window of the türbe (mausoleum), and its late-Seljuk style decoration.
The same design was used a century later for some windows of the Kaya Çelebi mosque, which lies 150 m to the east. The türbe is almost certainly not the work of Mimar Sinan; it is thought to date from 1587, the year that Hüsrev Paşa died during a military campaign in western Iran.
