The aim of this study is to review the multi-volume scientific publications and monographs (single and collective) from 1993-2021 that examine the sacred art of the Roman Catholic Church in Ukrainian territories. The methodology and specifics of the main works are clarified, and problematic issues and difficulties encountered by researchers during their work are identified. Methodology. The study employs an integrated approach that utilises scientific analysis methods such as systematisation and generalisation. It also combines historical, cultural, art historical, and theological methods. This approach is appropriate, considering the liturgical purpose of sacred art and the requirements set by the Catholic Church based on the Holy Scriptures. Research results. A review of scientific works in multi-volume publications, as well as individual monographs, suggests that the sacred art of the Roman Catholic Church in Western Ukraine was formed over many centuries. Researchers have studied over 500 shrines and tens of thousands of liturgical items of significant historical, cultural, and artistic value. Renowned scholars, including Jan K. Ostrowski, A. Betlej, T. Zaucha, K. Brzezina, P. Krasny, R. Quirini-Poplawski, J. Petrus, S. Lenartowicz, M. Biernat, M. Walczak, J. Skrabski, M. Kurzej, R. Nesteruw, T. Kukiz, and others (Polish edition), M. Buchek, I. Sedelnyk (Polish, Ukrainian edition), D. Antoniuk (Ukrainian edition), and others, conducted a comprehensive study, inventory, and attribution of these monuments. Scientific novelty. The obtained results highlight the challenges of studying sacred art monuments in Ukraine during the specified period. The specifics and methodology used by Ukrainian and foreign scholars in scientific research are identified through multi-volume scientific publications and monographs (individual and collective). Recommendations. Further historical, cultural, and art historical research is required to complement previous publications and enhance our understanding of the specifics of sacred art, particularly painting. This research will also reveal the methodology and technology used in creating these monuments. It is crucial to preserve these sacred monuments from destruction, especially during the period of military invasion by the Russian Federation since 24 February 2022
