This patron was Muzaffer Burucerdi, and the school (completed in 1271) studied physics, chemistry and astronomy. The architect is unknown but it's in a square Seljuk style, with a courtyard surrounded by cells. These are windowless, so you'd sleep in them rather than study. It fell derelict in the 20th century but has been restored.

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.
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.
