Područje na kojem je u VIII. stoljeću sagrađena crkva Presvetoga Trojstva naseljeno je od davnina. Prodor i afirmacija kršćanstva u Zadru koja se dogodila između IV. i VI. stoljeća, za grad i njegove stanovnike značilo je veliku promjenu. U to vrijeme grad dobiva svoga prvog biskupa, a sjeverno od rimskog foruma gradi se episkopalni kompleks. Nekoliko stoljeća kasnije, odlukom zadarskog biskupa Donata unutar zadarskog episkopalnog kompleksa dolazi do gradnje crkve Presvetoga Trojstva. Crkva je građena u dvije faze pri čemu prva datira u VIII., a druga u IX. stoljeće. Tijekom druge faze gradnje na građevini je izvedeno nekoliko značajnih zahvata. Prije svega potrebno je spomenuti kako je crkva tada dobila galeriju, sustav prostorija prigrađenih uz nju i narteks. Crkva Presvetoga Trojstva najveća je predromanička građevina u Hrvatskoj i po tome se ubraja u najvažnije primjere hrvatske, ali i europske kulturne baštine. Od XV. stoljeća crkva nosi ime biskupa koji ju je dao sagraditi – sv. Donata. Tijekom godina crkva je doživjela nekoliko pokušaja restauracije koji su zapravo prilično naštetili njenom izvornom izgledu. U ovome diplomskom radu predstavljen je prijedlog srednjoškolskog učeničkog projekta iz predmeta Likovna umjetnost posvećen crkvi sv. Donata u Zadru. Prvu fazu projekta čini učionička nastava koja obuhvaća samostalno istraživanje učenika u okviru grupnog i individualnog rada u kojem će se obraditi tri teme: Antički Zadar, Povijesne prilike u doba izgradnje crkve sv. Donata i Sv. Donat: Rotonda Presvetoga Trojstva u Zadru. Teme obrađene na učioničkoj nastavi prikazati će širi kontekst i obuhvatiti povijesno-društvene prilike koje su dovele do gradnje crkve. Drugu fazu projekta čini jednodnevna terenska nastava. U završnoj fazi projekta predstaviti će se rezultati istraživanja putem kratkog dokumentarnog filma koji će pripremiti jedna od grupa učenika. Projekt će se predstaviti nastavnicima, ostalim učenicima škole i roditeljima povodom Dana škole ili Dana otvorenih vrata. Ovim projektom, putem samostalnog ili grupnog istraživanja učenicima će se približiti okolnosti nastanka građevine što će ih potaknuti na vrednovanje nacionalne kulturne baštine. Također projektom će se upotpuniti ionako mala satnica predmeta Likovna umjetnost koja spomenicima nacionalne kulturne baštine ne pridaje dovoljno pažnje.The area, where in the VIII century the Church of the Holy Trinity was built, has been inhabited since ancient times. The penetration and affirmation of Christianity in Zadar, which took place between IV and VI century, meant a major change for the city and its inhabitants. At the time the city got its first bishop, while north of the Roman Forum the Episcopal complex has launched and well under way. The construction of the Church of the Holy Trinity, within the Episcopal complex in Zadar, started with the decision of the Zadar’s bishop Donat. The church was built in two phases, first one dating back to the VIII century and the second phase dating back to the IX century. During the second phase of the construction several significant developments were incorporated into the building design such as a gallery with a system of additional rooms next to it as well as a narthex. The Church of the Holy Trinity is the biggest Pre-Romanesque building in Croatia and it ranks as one of the most important examples of the Croatian and European cultural heritage. Since the XV century the church bears the name of the bishop who had initiated its construction – St. Donat. Over the years the church has undergone several attempts of restauration which were in fact not beneficial but on contrary quite damaging to its original appearance. In this graduation thesis a proposal for the high school student’s project within the Visual Arts course is presented. The aforementioned project is dedicated to the Church of St. Donat. The first phase of the project includes classroom teaching that consists of an independent research conducted by the students, both in a group or independently, and will cover three subjects: The Ancient city of Zadar, Historic opportunities during St. Donat's Church construction and St. Donat: The Church of the Holy Trinity. Subjects covered in the classroom will show a wider context and will encompass historical and social conditions that led to the construction of the church. The second phase of the project includes a one-day field trip. In the third and final phase of the project the results of the research will be presented in a short documentary that will be prepared by one of the student groups. The project will be presented to the teachers, other students as well as parents at the celebration of “Day of the School” or the school’s “Open Door” days. With this project and the student’s involvement in the research, the circumstances of the monument’s construction and the facts behind its commencement will give the students a unique opportunity to better understand it, which in turn will encourage them to truly value the rich national and cultural heritage. Furthermore, the project will help increase the insufficient hours dedicated to the Visual Arts class and increase the awareness of the significance that monuments as such bring to our national and cultural heritage
