Constructed after the fall of the Seljuks and the coming of the Mongols by Pervane Muhinedin Süleyman, a local potentate, the 13th-century Gök Medrese has also served as a hospital and a school.
Very few of the building's gök (sky-blue) tiles are left on the facade, but there are enough on the interior courtyard walls to give an idea of what it must have looked like in its glory days.
At the time of writing the medrese was closed for renovations.
