Tourism is a growing economic branch which for many countries represents major exporting product. It is a dinamic branch where changes are almost of daily nature which translates in a higher struggle with competition. The development importance of a tourist destination refers to creating prerequisites for tourism development of the country for that reason it is important to shape a tourist destination with the goal of atracting as many tourists as possible and to take best position on the tourism market. Dubrovnik is our most important and biggest attraction which has brought many adventages to the development of tourism in our country. All that can be contributed to the long history on the grounds on which Dubrovnik, today, is an atractive and unavoidable destination for many tourists. It is not all great when it comes to tourism, it leaves a permanent mark not only on the inhabitants of the city but also on the cultural-historical segment countless monuments but most of all on the nature that sorround as. Namely, today we have good and bad sides of tourism which we can notice and can say that they bring more harm than good to Dubrovnik. In this paper are higlihted all possible positive and negative influences of tourism on the development of the city also the effects resulting from them. In this paper I have decided to describe some of the events which have been taking place for a number of years and which have been improving the development of the city, both in cultural and every other sense. From recent times I mentioned nautical and cruiser tourism which is in Croatia in its eary stage of development in comparison to the rest of the world. Although some research have shown that the general attitude of the inhabitants is positive despite that cruise ships and nautical tourism are damaging the flora and fauna of the area. Despite all that Dubrovnik is a worls known and prestigeous Croatian destination, one of the leading european and world cultural-historical monuments and thus an atraction which with its recognizability every year brings hundrets and thousands of tourists. Dubrovnik accomplished all that things to the media , internet and a long history and also on the fact that it gives the tourist what they want. The media did the important step in promoting Dubrovnik in the world, different tipes of promotional mikses have improved the development of tourism in Dubrovnik which made it world known and brought many foreign tourist. Apart from foreign media an important part in the promotion have had domestic private and public companies which with their services bring a boost to the development of tourism or the hole country and especialy Dubrovnik. At the end when we add it all up we need to take in account that all this needs to blend in to the life of the city and that the race for profit does not take from Dubrovnik that what it had managed to conserver troughout its long history.
