Description from ArchNet: The Çifte Madrasa is so named because it consists of two adjacent four-iwan buildings oriented north-south. The one to the east was founded as a medical school by Sultan Giyaseddin Keyhüsrev (1192-1197 and 1205-1211) and the other was founded as a hospital by his sister Gevher Nesibe Sultan. The complex is not only the first Seljuk madrasa in Kayseri, but also the oldest hospital in Anatolia.

Kayseri

According to Shiro Takahashi, in the city of Kayseri there are a number of muqarnas with the same basic shape with different interpretations, all of the type "back on curve". Below is an overview of those different versions. A special variant is above a door in the Cifte Madrasah Gevher Nesibe hospital.

It looks like that the muqarnas runs straight up with a vertical unit. Furthermore, the second layer is closed at the corners with the special triangular building unit that occurs in all designs with this basic shape. Analysis and examples

Kayseri Cifte Madrasah Gevher Nesibe

Above a door of the Cifte Madrasah Gevher Nesibe hospital, a muqarnas with a special set of two non-standard building units has been realized. The set creates space within the square surface of the underlying layer for a smaller building unit on the next layer. As a result, the surface of a standard square is doubled in height.

Harmsen and Krömker describe this extraordinary unit because their software did not recognize its geometry.
