he matter of the origin and the time of the communal house's appearance in our country has long been studied. But, meanwhile the time of the communal house's appearance, which is in the Early Le Dynasty, received the consensus of most researchers, there are still many controversial opinions about its origin. This article contributes an interpretation of the origin of Vietnamese communal house. From the analysis of some evidence in the history books and Sino-Nom documents, the author suggests that the communal house originate from "Than Minh" communal house (where people gather to receive announcements or decrees from the royal court) and "Huong am tuu" ceremony (village ceremonies in spring and autumn), which are imposed by the Ming Dynasty to strengthen the ruling system in Vietnam in the early 15th century. This model was then received by Vietnamese dynasties since it was appropriate for village management and people reformation. Gradually, from an administrative and community site, the commnal house extended its function into religious beliefs and become an indispensable symbol of Vietnamese villages.
