Suli Pasha Khatun
Suli Pasha Khatun (died 1339) was a consort of Ala al-Din Eretna, founder of the Eretnid sultanate in central Anatolia. After her death in 1339, Eretna built the Köşkmedrese on Mount Köşk southeast of Kayseri in her memory.
Originally a Sufi khanqah, it became her tomb. Eretna, his son Muhammad I and his grandson Ala al-Din Ali were later buried there as well.
