The site is located on Oc Eo field, about 22m north of Go Cay Thi A structure. This is an oval mound of land about 300m2 wide, high in the east-southeast, sloping in the west-northwest, about 1.5m high above the surrounding field surface.
In 1928, French researchers discovered the statue of Vishnu at the site of "Go Chon Cua" (now Go Cay Thi B). In 1944, archaeologist Louis Malleret, while excavating the Go Cay Thi site, noted the existence of a second structure located on "Go Chon Cua" (or "Golden Vault") to the north of Go Cay Thi A site.
The excavation in 1999 at Go Cay Thi A site basically revealed the foundation of an architecture built of bricks and stone on a reinforced soil foundation, with a structure consisting of 2 wall rings as follows: The outer wall is built of brick with a rectangular plan (16.70 x 10.4m), bent twice at the opening on the east side. The closed rectangular inner wall is built of stone (10.08 x 6.7m).
The central part of the architecture is a rectangular ground measuring 6.7 x 4.4m. From a depth of 2.45m to 2.90m, there is fine clay, mottled with reddish-gray color, and a flat round tin artifact, shaped like 3-4 coins stuck together, was found; In addition, orange agate beads and 3 green glass beads were also found. From a depth of 2.90m down is yellow-gray infertile soil with many alum holes.
New documents collected from the large-scale excavation and exploration in 2010 at Go Cay Thi site have helped to basically determine that Go Cay Thi site has two types of sites: residential sites and religious architectural sites belong to two continuous stages of development, dating from the first to the seventh century. The site was ranked a special national site in 2012.
