The Napa site in Barangay Tuhian, Catanauan is a very significant place for archaeological research. Most of the jar burials found in Catanauan were recovered from this site. In the 2008 excavation, a lot of jar burials with their human remains were found in Locality 1, Napa site, specifically in trenches 4 and 6. The jars found were mostly earthenware. Different types of coral slabs and rocks served as jar covers. The jars were used for primary and secondary burials. Paz, et al. (2008) inferred that people “went back to uncover the jars, take out the human remains in the jars, and when events dictated, a new body was placed in the old jar”. Some excavated jars were also used for child burials. Aside from human bones, different-colored glass beads, gastropods and fragments of metal were found inside the jars. Boat-shaped burial markers were also found in the site.
