Ghiyath al-Din
The complex takes its name from the princess. The medrese within is known under a variety of names: the Gevher Nesibe Medrese; the Çifte Medrese (Twin Medrese); or as the Gıyasiye Medrese, after Ghiyath al-Din Kaykhusraw I, who was responsible for its construction. The tomb within the medrese is said to belong to Gevher Nesibe.
