The theme valorisation of city-forming structures is an extensive and general problematic issue which deals with the "city improvement". The dissertation thesis is further narrowed to the phenomenon of "Urbanity" and "Urban Character" which can be often encountered in the literature specialised in urban design. However, this term is not accurately specified or objectified. The "Urban Character" has much in common with the genius loci, ambience and the feelings in the human unconsciousness. These feelings are caused by the environment and spaces that surround us. A closer examination of the causality of this problem is necessary in order to discover new findings from which the cities could benefit and "manipulate" people in a positive way. This may help the cities increase their credit. The thesis in its theoretical section defines the term "Urban Character", discusses the difference between "Urbanity" and "Urban Character" and describes where and by which elements the Urban Character is created. The research further documents and highlights the factors of Urban Character that affect the ambience and secondarily the feelings of visitors to a certain area/space in the city. In the experimental part of this work, there is a proposed evaluation of the individual factors according to their impact on the quantity and the movement of visitors in the environment affected by them. Adding a value to each urban factor on the particular example of Bratislava's axis, the theoretical hypothesis are verified. The results of this research are describing the factors of Urban Character and the theoretical evaluation method of urban structure that defines the potentials, limitations and problematic locations of the structure.
