Research on Changes of Spatial Structure Genotype of a Former Artillerymen’ Military Town of Kaunas Fortress

Immovable cultural heritage creates a background for sustainable cultural development of cities. As a cultural artefact, it appears in two-fold situation in the above-mentioned context. Firstly, the continuity of the valuable features as carriers of cultural content should be preserved. Secondly, the possibility of the evolution (functional, spatial or social) of the object should be assured. Now the valuable features of the immovable cultural heritage are described in a static, quantitative ways with focus on phenotype, e.g. spatial volume, place, details of architectural style, number and places of windows, etc. Such type of description without any argumentations is practically closing any possibilities for further evolution of the protected objects. It is especially true if we speak about urban valuable structures. The authors of the article present a proposal for dynamic, genotype oriented modelling of the possible evolution of the former military town of Kaunas Fortress as an example of immovable urban cultural heritage. The model is based on the evaluation of changes in the cognition of urban structure with presentation of complex numerical values. Research included the following parts: historical urban development analysis of heritage territory, current state analysis, investigation and modelling of territory spatial structure genotypic changes. The results of the presentation demonstrate the limitations and subjectivity of the present system of description of valuable features of the objects of immovable cultural heritage and present the possible way for the improvement of the situation.
