Fritz Gause describes its predecessor as a Mittelschule in Oberhaberberg which moved to Hintere Vorstadt in 1900.
[1] In its entry on the Vorstädtische Realschule, the Statistisches Jahrbuch der höheren Schulen states it developed from an elementary school founded in 1815 and known as the Domschule (referencing Königsberg Cathedral) since 25 July 1835.
[2] On 15 October 1874 this school was acquired by the city of Königsberg and renamed the Kneiphöfische Mittelschule.
The new red brick building in Vorstadt, located where the St.-Georg-Hospital stood on Böhmstraße[3] near Jahrmarktplatz and St.-Georg-Hospital, contained a large gym and auditorium.
A number of students also commuted to the school, as it was located near the city's Hauptbahnhof (now Kaliningrad Passazhirsky railway station).
