Archaeological excavations at Kaxil Uinik and Ayiin Winik in Belize have revealed a Late Postclassic altar and evidence of ongoing ritual activities by the Maya people, despite the decline of their civilization around A.D. 900. The findings, published in Latin American Antiquity, indicate that Postclassic Maya individuals continued to visit these abandoned sites for religious purposes, resetting monuments and leaving offerings. Researchers observed that the Postclassic social structure diverged from earlier systems, yet long-standing religious practices persisted. At Kaxil Uinik, they found 'Chen Mul' incensario fragments, likely left as offerings, while the altar at Ayiin Winik consisted of clustered ceramic fragments around limestone blocks. This altar is notably the first of its kind discovered in the region. The study emphasizes the need for further research to refine dating methods and potentially uncover more Postclassic altars, enhancing understanding of the Maya's enduring cultural practices.
