As part of the artistic heritage of Senj, Podgorje, Gacka, Lika and the southern parts of the Modruš area in the 17th and 18th centuries in the thesis, after the autopsy during the fieldwork, the selection of art was made for the needs and the expected framework of the paper and narrowed down to the topic of Senj as the main centre and the only city with a continuous history without conquest and displacement. Going through the literature and contemporary sources, it was primarily the 18th century as one of the rich artistic production that has survived in some form to this day. The city history is presented briefly with the most significant events related to the main body of the work. The group of profane architecture and the specificity of relations to the Central European models is first studied. Then, a significant part of the work is devoted to the interventions of the cathedral as the baroque monument of the utmost significance of the time and a model for many solutions found in the equipment of branch churches that have mostly disappeared. The last part consists of two monastery churches and an overview of the remains found in The Sacred Heritage Foundation that wasn't in the context of the original sites. In the end, a review explains the demographic changes and how they reflected in the post-war reconstruction and preservation of the cultural heritage of Senj, as well as an overview provided for the writings in the professional literature and the method of study. The concept and focus of the paper became the reconstitution of the 18th-century Senj and its most significant buildings. As an amendment, pictorial material for illustration and comparison examples made in the study was added, as well as a catalogue of movable heritage with listed basic information and recorded current state of the works.
