Gevser Nesibe Şifahanesi / Gevser Nesibe Hospital
Gevher Nesibe was an early 13th century princess of the Sultanate of Rum, the daughter of Kilij Arslan II and sister of Kaykhusraw I. Gevher Nesibe is also the namesake of a magnificent complex at Kayseri comprising the former hospital, an adjoining medrese devoted primarily to medical studies, and a mosque in Kayseri, Turkey. The complex (külliye in Turkish) that she endowed, is considered one of the preeminent monuments of Seljuk architecture.
