During the period of Austro-Hungarian rule (1878–1918), Mostar’s city council cooperated with the Austro-Hungarian administration to implement sweeping reforms in city planning: broad avenues and an urban grid were imposed on the western bank of the Neretva, and significant investments were made in infrastructure, communications and housing. City administrators like Mustafa Mujaga Komadina were central players in these transformations, which facilitated growth and linked the eastern and western banks of the city. Noteworthy examples of Austro-Hungarian architecture include the Municipality building, which was designed by the architect Josip Vancaš from Sarajevo, Residential districts around the Rondo, and Gimnazija Mostar from 1902 designed by František Blažek.
