The survey studies dated 1914 show that the structure was functioning as a madrasa.

In the 1950s, when Vatan Avenue was opened, the structure was fully revealed.
It was restored between 1958 and 1962.
In 1968, it gained the function of the Turkish Calligraphy Arts Museum.
In 1983, the works in the museum were moved to the Bayezid Madrasa.
After this stage, it was used for a period as the Health Foundation Şadiye Hatun Clinic; as of 2013, it served with the function of a polyclinic affiliated with Medipol University.

Prominent Features:
It is also known as the Halıcılar Köşkü Madrasa, the Sultan Selim-i Kadim Madrasa, and the Yenibahçe Selim Madrasa.
The structure, measuring 28.50 × 46.00 meters in its outer dimensions, has a layout with two courtyards, an outer and an inner one.
Within the arrangement surrounding the inner courtyard in a U-shape, there are 19 cells and 1 iwan.
The square-planned classroom is located on the entrance facade; it was placed so that its porticoes remain within the inner courtyard, while its main mass projects into the outer courtyard.
Because of the rise in the road level, the madrasa courtyard now remains below the street level.
The original fountain has not survived to the present day.
