This rampart had Gopura in two-direction (East and West) entrances that are connected by the other laterite ramparts. In between rampart 2 and 1, at the Northeastern side near the rampart 1, there was a rectangular pond (42.10m x 34.20m). The bottom of the pond spread by laterite and surrounded by the stepped stairs. The small stairs of the Southern side are made of sandstone.

Now the pond is empty during the dry season. When we enter from the Eastern Gopura on either side of the road, we see two sanctuary hills were built on high terrace with the tracks of the round column made of laterite lining up in 0.40m height.
