The goal and the result of the dissertation thesis is a monographic elaboration of the urban-architectural development of Bratislava in the Middle Ages and during the beginning early modern times (circa between 1250 and 1550). The author has created a synthesis based on an analysis of written historic sources, younger map plans, image sources (vistas, engravings, historical photographs) and much of the existing archeological and historical research. The result of the work, besides the written synthesis (a catalogue), is also a graphic elaboration of a number of phenomena (e.g. the prevalence of certain types of portals or types of houses in various parts of the city intra muros). The author has comprehensively and graphically made the acquired findings available via digital 3D-model of the city. The model represents a sum of currently available information, which can be added, updated, or even corrected without any problems in the future, thanks to the digital technologies – depending on the progress of further research. The work therefore represents conservational-historical topography of the city, together with digital 3D modeling of the space as well as the individual buildings. The main advantage of the written part is a synthesis of partial information into a greater whole which will enable to pose new questions, and to give new answers. The main benefit of the 3D-model is the clarity of graphical output and the feedback possibility for archeologists, conservationists, and other specialists.
