The evolution and cultural significance of the Jatti Miriek grave markers in Sarawak, Malaysia, are examined in this paper, along with their relationships to the Bajau Sunduk from the Sulu Archipelago and the Batu Aceh markings in Indonesia. With historical research and a visual comparison analysis, it seeks to understand the complex interplay of Islamic, cultural, and architectural influences on the Jatti Miriek grave marker designs. Examining 167 markers and interviewing local experts were made possible by doing fieldwork at 13 sites in Miri, Sarawak. The detailed information on Jatti Miriek grave markers is then examined with that of Batu Aceh and Bajau Sunduk using a visual analytical comparative study. The results show that Bajau Sunduk later influenced Jatti Miriek's designs, especially concerning materials and motifs, which originated in Batu Aceh. Studies of Southeast Asian cultural heritage and art history can benefit greatly from this research's improved comprehension of the socio-cultural influences forming these artifacts.
