In the Project: "Research on Óc Eo - Ba Thê, Nen Chùa archeological site (Óc Eo culture, Southern Việt Namy1 conducted by the Việt Nam Academy of Social Sciences, during 2018 - 2020, the Việt Nam Institute of Imperial Citadel Studies was delegated a task of earchaeological excavation and research on the site area Nền Chùa (Kiên Giang) in an area of 8,067m2. As a result, a cultural layer was found in two areas: one is on the high mound with 02 cultural layers, the above architectural layer and the lower settlement layer; and the other includes 01 settlement layer in low-lying land. There were 23 relics unearthed, including: Hindu-temple architecture, "Sacred Pillar" site in front of the temple, wells, lakes, traces of brick yard on the common bank between the two lakes and 13 residential traces of houses-on-stilts around the mound foot focally along the ancient fountain. The found artifacts are rich in materials, forms and functions, including stone, metal artifacts, ornaments and ceramics. In terms of dating, the settlement layers and architectural remains of houses-on-stilts are around the 2nd - 3rd centuries AD and the cultural layers. Relics are rich in materials, types and uses, including stoneware, metalwork, jewelry, and ceramics. In terms of chronology, the resident culture layer and stilt house architectures date from the 2nd - 3rd centuries AD and the cultural layer containing architectural remains are from the 4th to 6th-7th centuries AD. These are very important new discoveries, which serve as evidence to prove the temple Nen Chùa site was a major population and religious center. It is identified as the point connecting the two spaces: urban and seaport ones in the cultural and economic interactions with Southeast Asian island countries; the gateway for trade between the ancient Óc Eo town and the outside world via sea.
