On the western part of the old city walls, guarded by three bastions and gates, this square was initially a marketplace, which was going to be moved to the central square. Eventually, the marketplace was moved closer to the railroad, in the current location of Mihai Viteazul square. Thus, at the end of the 19th century and the beginning of the 20th century the walls and gates of the city were demolished, and a small park was arranged in this square.
Later, new buildings were erected here, such as the National Theater, the Orthodox Cathedral, the building of the Chamber of Commerce and Industry, in the Art Nouveau style (today, the office of the Cluj Prefecture); the building of the old “Unió” Masonic Lodge (no. 7 Avram Iancu Sq.); the building of the old military garrison (today, the building of the County School Inspectorate, also known in the oral tradition of the city as the “red building”, a name earned by the red brick walls of the building); the Palace of Justice, where the Court of Appeal and the Tribunal are housed; the EMKE Palace (Hungarian Cultural Association of Transylvania), later purchased by MÁV (Magyar Államvasútak, Hungarian State Railroads), currently the headquarters of the CFR Regional Office; the building of the Archbishopric of Vad, Feleac and Cluj, which houses the Faculty of Orthodox Theology and the building of the Protestant Theology, on the old site of the Reformed Church’s Prayer House. http://www.visitclujnapoca.ro/en/atractii-turistice/monumente-si-complexe-arhitectonice/avram-iancu-square.html
