In the middle of the 19th century, Pula was declared the main Austrian (Austro-Hungarian) war port, after which the rapid urban development of the city began. Along with many residential, social, industrial, infrastructural and military buildings, the Pula fortification system was built in several rings around the city, due to the need to defend the main military and naval port. With the historical development of circumstances and the collapse of later governments, the fortification system loses its purpose and remains abandoned to the passage of time. The paper considers the architectural cultural heritage, which, in addition to its specific cultural and historical significance, also represents an integral part of human life and the environment, which is why it is necessary to preserve it through active use. European examples of the revitalization of fortification architectural heritage are cited as good practice. This paper also considers the possibilities of revitalization and new forms of using the fortification system of Pula as a cultural and tourist product, which will be open to domestic and foreign visitors and the local population and will have a positive impact on the attractiveness of Pula as a destination of cultural tourism. Furthermore, the author of this paper suggests new ways of using individual forts as well as new ways of connecting the forts into local cycling and walking routes.
