Dalmatian cities are known for their rich cultural heritage and history, during which different governments and states have changed. Since in the past there was a constant threat of military sieges and attacks, many governments built fortresses and forts to defend themselves against enemies. Today, having lost their original purpose, fortresses are taking on new roles. These roles are focused on cultural and event tourism. Cultural and event tourism is developing more and more in Croatia and is becoming more and more popular because instead of promoting globalization in mass tourism, which is becoming an increasing problem, it emphasizes the preservation of tradition and cultural heritage. The connection of cultural tourism and fortresses is logical, and it is precisely because of this that many fortification revitalization projects have been realized. The aim of this work is to present successful projects of renovation and modern use of fortresses that lead the policy and strategy of sustainable tourism, digitization and preservation of cultural heritage. In addition, the paper also provides data on the potential impact of revitalization on tourism in that area.
