In this work, through the prism of ancient monuments, primarily latin inscriptions, the story of antiquity in the Bujština area is told. This relatively small area located in the northwest of Istria has a very rich history, dating from prehistoric times to the 1960s and the development of tourism. The ancient roman period was often marginalized in research, thus this was one of the main reasons for this thesis. After consulting ancient writers who write very modestly about these lands and ancient itineraries, the paper describes various ancient roman sites, some of which are incorporated into modern cities, and some are settled out independently. The roman inscriptions were processed in the form of a catalog, with all the necessary information about them, as well as some more detailed onomastic analyzes. The catalog includes all known inscriptions from Umag, Novigrad, Buje, Oprtalj, Brtonigla and other smaller settlements and villages. When all this is summed up, one finally gets a some meaningful and complete picture of the ancient period in Bujština, as well as their colorful inhabitants, including rich and poor, slaves and freedmen, soldiers and property managers. It also discusses various issues that are often associated with particular inscriptions and names on them, and in addition to theories and different theses, an attempt is also made to provide a solution.
