The aim of this study is to give an insight into the phenomenon of Nowa Huta, which has been one of Krakow’s districts since 1951, although in 1949 it was planned as a separate city. Particular emphasis in this part is placed on the realisation of the potential of the XVIII District after the changes in the political and economic system that took place between 1945 and 1989. One of the ideas of Tadeusz Ptaszycki, the chief architect of Nowa Huta, was to implement the principles of the ideal city and garden city, i.e. a city with small, low-density buildings and a predominance of green areas. However, industrialisation happened so quickly that it nearly led to the extinction of many plant and animal species. Fortunately, the development did not invade the Nowohucka Meadows, allowing residents to enjoy the benefits of this unique natural site. In 2023, Nowa Huta was declared a historical monument, which gives it additional protection from poorly thoughtout investments and supports the development of cultural tourism, historical education, and the creation of cultural trails. Krakow is also covered by a sustainable tourism policy, which supports its cultural heritage and protects the natural environment. The principles adopted combine the needs of tourists with conscious consumption and long-term planning that takes into account ecological solutions and the comfort of residents in accordance with the ‘respect Krakow’ motto. It is also important to engage the local community and visitors in spreading the message about Krakow on social media, for example by using the hashtag ‘#krakow’.
