In the 1913–1914 academic year, the school was upgraded to “sultani” status; a wooden additional floor was added to the building as needed, making it three stories high.
During World War I, the building was used as a hospital and also served as a munitions production site.
The building was burned in the Fatih fire on 31 March 1919 and remained in ruins.
The ruined building was repaired in 1922 and reduced to two stories; it reopened for education as a two-story building in the 1924–1925 academic year.
Due to increasing needs, a 16-classroom annex was constructed in the side garden and opened in the 1996–1997 academic year.
In the 2005–2006 academic year, the school was converted to an Anatolian High School.
Prominent Features:
The school is also known by the names “Gelenbevi İdadi,” “Gelenbevi Sultani,” “Gelenbevi Middle School,” “Gelenbevi High School,” and “Fatih Gelenbevi Anatolian High School.”
The land was purchased by the Ministry of Education, and the school was registered under the name “Gelenbevi İdadi.”
The decree assigning the school name is dated 29 January 1911 and belongs to Sultan Mehmed Reşad.
The land was also known as “Gelenbevi’s Garden”; sources indicate that there were two water wells on the site.
