An older madrassa, completed in 1217 in Seljuk style - so it set the standard that the later trio were aiming to surpass. It contained a hospital and medical school. Within is the tomb of its founder, Sultan Izeddin Keykavus I, and the medrassah tilework has been restored.
Şifaiye Medresesi is a medrese built in 1217 in Sivas, Turkey. It bears typical Seljuk features and was built by the Rûm Seljuk Sultan Kaykaus I, who was known for his fondness for the city of Sivas where he spent the large part of his period of reign.
The third of the trio, this was built in 1271 by Vizier Sahip Ata Fahrettin Ali. The name means "celestial" or blue, for its tilework. It has an imposing gatehouse with twin minarets leading to a courtyard and cells, nowadays shops. The building originally had a second story, long gone.
This former high school was where Atatürk consolidated his power base in 1919 and launched the struggle for independence. It now hosts three museum collections: congress with mementoes of that era, ethnography, and archeaology.
