Most of the great cities in the world once depended on their rivers for purpose of trade, and communications, but industrial age has frequently left these places without a heart. At present, Slovakia, as well as Serbia, is in the process of dynamic changes, which influence our lives and our cities. These changes bring positive, but also negative impact on the cities. This current situation was a reason to make a specific research, to analyze it and to try to find a new solution or principles in planning process of river waterfronts. This paper is analyzing the relationship between the city and the water. It compares the present state of waterfronts in Novi Sad (Serbia) and Bratislava (Slovakia), as regions of Europe significant by their hydrograph. Waterfront of Danube is linear path, which we can understand as a region of linear entity, long a few hundred or even thousand kilometers, from it's origins to the delta. Also, this relative indeterminate spatial concept can be considered as part of this big area. Because of this, it's very important to underline, that this research work were analyzed only Danube waterfronts in parts, where this river flows across the two cities: Novi Sad and Bratislava. Through analysis, different criteria are being used: characteristics of present urban morphology, distribution of functional programs, social aspects, and the relation to environment, historical identity and urban memory of space. The paper critically address especially water's edges (how are riversides of Danube transformed by urban and architectural development today) and is trying to develop theoretical framework for redesign of public space on Danube waterfronts in Bratislava and Novi Sad. Main objectives were: 1. to evaluate importance of the history and facts, that influenced shape and changes of the Danube waterfronts 2. to map the current situation of waterfronts in Bratislava and Novi Sad and compare these cities according the selected criteria 3. to get an impression of similarity of the waterfront problems in these two cities and to compare them with other European cities 4. to give a suggestion for the flexible model of physical waterfront structures for European city, so that the cities are functional to their citizens and allow all changes with places reorganization (land use) 5. to define the functions that will be preferred at the Danube walking paths in present time It's not easy to shortly present the current situation at Danube waterfronts of Bratislava and Novi Sad, because of the fact, that through ages, many builders and styles left their marks at this land. It's also important, that development of these parts of cities was not continuous and the same part of area was not always upgraded. This has resulted in linear but non consistent entity in meaning of connection to the river, architecture, traffic solutions, landscape, etc. Nevertheless, heterogeneousness and natural surrounding are still dominant factors in this area and promenade, which is located close to the river, groups various architectural forms with different functions into one coherent entity. The present situation of waterfronts of both cities is a result of their history and influence during their development. Revitalization of places should start with evaluation of the existing conditions and factors that influenced them. Many destructive impacts and events in previous periods affected Bratislava and left the traits of lassitude in active exploration of this area. On the other hand, waterfronts in Novi Sad passed the war destruction and were not revitalized to satisfaction of citizens' expectations, due to lack of resources. But, in both cities, these zones became central and very important for everyday life of their citizens, so there is an intensive need for their future redesign and revitalization. In spite of all that, spotted areas are very attractive and important parts of cities Bratislava and Novi Sad and play a great role in the image of these two European cities.
