The master's thesis includes architecture presented as art and the characteristics of sacred architecture in the Romanesque, Gothic and Renaissance periods. Furthermore, generally about the city of Sibenik and the magnificent Sibenik Cathedral of St. James, what significance it had for the people of Sibenik at the time, in how many stages was it built and what did each stage or period contribute to the construction of the cathedral as we know it today. Then it was shown how cultural heritage and architecture contribute to the teaching of Fine Arts in the first four grades of elementary school. The goal of the research is how to encourage students in class to research architecture. The research was carried out at Juraj Dalmatinac Elementary School in Sibenik during the Fine Arts classes in class. At the end of each Art class, there will be a conversation with the teachers of their classes and their own observations during the classes will be discussed. All four classes were given the same art motive, and each class used and realized its work with a different art technique. The students of the first grade showed the western part of the Sibenik Cathedral of St. James in the felt-tip pen drawing technique. In the second grade, students used the tempera painting technique to show the floor plan of the Sibenik Cathedral. Students of the third grade using the graphic technique of monotype, showed the cathedral of St. James from every angle, and in the fourth grade, using the sculptural technique of didactic unshaped material (boxes, packaging, etc.) divided into groups, they built their own cathedral of St. James. The students of all four classes were interested in processing the motive of the Cathedral of St. James's motivation was not lacking in their works. The master's thesis also includes your own written preparations for holding an Art class in class
