This paper presents the inscriptions of the Greek Catholic Church in Croatia. A tour of the Greek Catholic churches and chapels established their topography and was arranged according to the organization of the Diocese (Eparchy) of Križevci. Each discovered inscription was accompanied by a photograph, original text, translation, time of creation, material, language and script, and accompanying commentary. This resulted in a catalogue of 195 units. A discussion was held on the collected inscriptions afterwards. It has been established that the Byzantine linguistic and graphic tradition (Church Slavonic and Greek language, Cyrillic and Greek script) significantly prevails in inscriptions with liturgical purpose (icons, iconostasis, shrouds, frescoes, etc.), i.e. that the inscriptions have a different purpose and content, such as celebrating anniversaries, important events, building constructions, etc. often in the languages and scripts of the community to which the sacral building belongs (Ukrainian, Ruthenian and Croatian language; Cyrillic and Latin alphabet). It was also established that there are many more inscriptions in the vernacular for liturgical purposes in Slavonia-Srijem than in the Križevci Vicariate because there are prominent Ukrainian and Ruthenian communities that have liturgical services in their languages. The Greek Catholic sacral heritage in the eastern part of Croatia was significantly damaged in the Croatian War of Independence, but most of it was faithfully restored in its original form, thus emphasizing that there is no interruption of continuity and departure from tradition. This, of course, also applies to inscriptions in that part of Croatia, because in most cases there is no deviation from the Cyrillic alphabet. There are more frequent inscriptions in Croatian language and Latin alphabet in the Križevci Vicariate, but there is no Latinization of the Vicariate there either, because these inscriptions are distributed over time.
