Dalmatia, a region in the southwest of Croatia, has a long history of building fortresses, dating back to ancient times. In the Middle Ages, fortresses were used to protect against the attacks of the Turkish army, while in recent times they were used as a means of controlling and defending the territory during the wars in the former Yugoslavia. Several famous fortresses in Dalmatia are: Fortress of St. Nikola in Šibenik, Klis fortress near Split, Bokar fortress in Dubrovnik and Mirabela fortress in Šibenik. These fortresses were built in strategic places with a view of the sea and the surrounding areas, and today they are a significant tourist attraction. Basically, the fortresses in Dalmatia represent an important part of its history and culture, as well as a significant tourist potential for the development of Dalmatia. The Dubrovnik fortress was taken as the starting point in the research. The Dubrovnik fortress is one of the most important monuments of the city and represents an important example of fortification architecture. The fortress was built in the 13th century, and was later expanded during the Renaissance, when it was rebuilt to strengthen the city's defenses. The Dubrovnik fortress consists of several towers, walls and palaces, with a beautiful view of the sea and the city. In the Middle Ages, the Dubrovnik fortress was an important part of the city's defense system and served to protect the population and the city from enemy attacks. Fortress architecture encompasses many styles and techniques used in the design and construction of fortifications. Depending on the time period and geographical area, the architecture of fortresses can vary from simple walls and towers to complex complexes with bastions, towers, palaces and other structures. In the early Middle Ages, fortresses were simple structures with high walls and towers for defense. Later, during the Renaissance, fortresses began to be designed with wider bastions and angled walls, which allowed for a wider view and better protection. Fortresses in the Baroque style often had grandiose facades with decorations, which served as a symbol of power and authority. More recently, fortresses began to be designed with a functional and technological approach, including underground communications, irrigation systems and other technological innovations. In any case, the architecture of fortresses represents an important aspect of the construction history and reflects the political and military priorities of the time. Today, some of the most famous fortresses in the world are the works of great architects and are significant tourist attractions.
