Şeyhülislam Hayri Efendi Primary School

The Tetimme madrasas functioned historically as lower-level educational structures completing the Sahn-i Seman madrasas.
A document dated 1783 records that the tetimmes were renovated according to their former state.
While the structures on the Mediterranean side of the tetimme madrasas were demolished during the opening of Fevzipasa Avenue in 1928, the structures on the Black Sea side were merged and largely lost their original state.
The remaining tetimme structures were rebuilt by the Foundations Administration in the early years of World War I and used as madrasas for a period.
The structure became ruinous after the 1908 Circir fire; Sheikh al-Islam Hayri Efendi had repairs made and the structure was used for various housing and settlement needs for a time.
The school opened as a primary school in 1933; from 1949 onwards, it was known as the Sheikh al-Islam Hayri Efendi Primary School and was merged with Ali Kuscu Primary School in the 1996–1997 academic year.
The structure is currently used as a primary school building.

The structure is part of the educational building group known as the Tetimme madrasas; it is also referred to as Musile-i Sahn and by the name medrese-becce mentioned in the complex endowment.
The Tetimme madrasas were designed within an eight-madrasa layout arranged in parallel and separated from the Sahn madrasas by a narrow street in the background, intended to prepare students for the Sahn-i Seman madrasas.
The merging of the tetimme structures on the Black Sea side is the primary physical transformation that reduced the original legibility of the madrasa cells and the settlement scheme.
The building group is significant in the context of historiography and the history of science, as it sits at the core of the early Ottoman education and science center in Istanbul alongside the high-level Sahn-i Seman madrasas of the Fatih Complex.
