Conference activity is one of the main cornerstones of the city's development, both in terms of prestige and economics. It is known that congress activity promotes the development of economic, scientific and cultural ties, which, in turn, tend to improve the quality of the citizens' life in various respects, such as, for example, the economic impact on local service providers and, consequently, on the city welfare. Furthermore, many other aspects, not directly related to the congress world, take advantage from that: just to mention some of those: general security; regional and international connections; tourism and leisure; increase of local scientific, cultural and business activities.
