THE RESIDENCE FORM ON EMBANKMENT FOUNDATIONS IN THE PREHISTORIC AGE AT THE RACH NUI HISTORICAL SITE THROUGH THE DATABASE OF AN EXCAVATION IN 2012

Abstract

The embankment residence is one of the typical forms of the prehistoric sites in Long An Province. This type of historical site reflects the adaptive ability of the prehistoric people to nature, and their capability to affect and modify the physical environment to match the needs of existing as well as the development level of the community in this prehistoric era. The ancient habitation area at Rach Nui relic was made up of clay, sand, mollusks, and forest trees. The ground was rammed and had many hard burns to form dry settlements. An excavation in 2012 identified a residence relic consisting of tens of embankment stages and reinforcement of the ground. On this excavation site, there were the vestiges of plant-roofed structures that were the residences of ancient people for more than 200 years. During this period, 13 major construction phases were identified, whereby each foundation and all its structures were successfully replaced.
