This diploma thesis is entitled "The Fate of Pula's Architectural Heritage from the Time of the Habsburg Monarchy" and it provides insight into the development of the city of Pula from its foundation to the present day, focusing on the time when the Austro- Hungarian Empire ruled the city. The main part of the paper covers the urban and social development of the city during the Monarchy in the period from 1867 to 1918. Special focus is given to the buildings that were representative examples of the Austro- Hungarian method of construction, such as: War Port with Arsenal, Hydrographic Institute of the Imperial and Royal Navy, Observatory, Naval Club, Naval Library, Naval Church, Naval Hospital and the Market, and their fate is briefly described all the way to the present day. As Pula had its "golden age" during the Austro-Hungarian Empire, i.e. the greatest development progress of the city in every respect, it was important to mention the main types of transportation of the city's population, and the emphasis was placed on the electric tram. Likewise, special mention was made of the Naval Library, which still has its role in society today, and the Observatory, which is still in use. At the very end of the paper, an analysis was made of the following monographs dealing with the history of the city of Pula: Pula od najstarijih vremena do danas s okolicom (Pula and Its Surroundings from the Ancient Times to the Present Day) by Vitomir Ujčić from 1963, Pula tri tisuće godina grada (Pula Three Thousand Years of the City) by Krešimir Čuturilo and Mario Kalčić from 1984, Pula oduvijek (Pula Since Forever) by Josip Bratulić from 2001 and Pula: grad dugog trajanja (Pula: a Long Lasting City) by Igor Zirojević from 2017. The goal was to compare the parts of the text of each monograph dealing with the rule of the Habsburg Monarchy in Pula, and to show how the authors described Pula from the time in which they created the monographs, and whether there were any significant differences in the descriptions of buildings, life and other components of the city. When we look at all the events that the city has gone through during its existence and under the rule of various states and rulers, we can conclude that Pula is a truly special city whose glow never fades.
