NOVI MAGISTRAT Jože Plečnik, progetti per il centro monumentale di Lubiana

This research work analyzes the theme of the architecture of the city and aims at establishing, by studying the urban project of the new town hall in Ljubljana made by the Slovenian architect Jože Plečnik, the idea that the construction of the city must be carried out through a type of architecture directed at the planning of collective urban spaces. The plan for the new town hall building, drew in three versions – 1932, 1939, and 1940-41 –, is part of a large set of plans concerning the area that Plečnik defines to be the “osrčje” (heart) of Ljubljana, that is, the central area within the castle hill and the distinctive arc of the Ljubljanica River, on the eastern boundary of the old “mesto” (town). Among the Plečnik's projects on urban scale for Ljubljana, the above-mentioned plans, unbuilt and scarcely published, must be considered to be ones of the least known, despite their importance in the professional activity of the architect. The work consists of three parts: the first part describes the background of theories and projects which shaped Plečnik's urban culture, during the years of his education in Vienna and before the beginning of the planning activities this work focuses on; the second part studies the plans for the “heart” of the city; the third part investigates the plan for the new town hall building by means of the graphical reconstruction of the three plan versions made by Plečnik, and it provides insights into the relationships among form, significance and motivation of his work. Since the plans have never been built, the digital tridimensional reconstruction of the building models allowed to show unknown spaces and confirm that Architecture has a particular significance when its goal is the planning of collective urban spaces.
