This work is concerned about the problematics of the architecture created in the context of totalitarian regimes of the 20th century. It is focused in more detail on the topic of representative urban ensembles, which are being explored through the object of the Námestie slobody (the Freedom Square) in Bratislava. The work is divided into four chapters. Chapter One illuminates the field, goals, terminology and hypotheses of our research. It explains the reasons behind the choice of the main case-study object, and brings about the overview of the published bibliography in the field as well. Chapter Two contains two additional case-studies of objects, development of which is compared to that of Námestie slobody. These objects are the Sheshi Skënderbej (the Skanderbeg Square) in Tirana and the Trg republike (The Square of the republic) in Ljubljana, which were constructed in similar manner as the central political squares in the context of authoritarian regimes. Chapter Three is a case-study focused on the main object of our study. The development of the Square is followed on various levels: specific programs of construction, the relations of style, form and ideology and against the background of changes of the architectural profession itself. Chapter Four is a concise summary of the developments of Námestie slobody after 1989, its public reception and potentials of functioning as a distinctive cultural heritage. The concrete methods of the heritage protection are the topic of further possible researches.
