The original form of the laterite chedi cannot yet be identified since it is covered by parts of the brick chedi that has not been totally excavated. However, the brick chedi, the one that is similar to Phra That Phanom, is believed to be constructed in the reign of King Chaiya Chettha Thirat. The construction is mentioned in the Lan Chang chronicle. The square monument with 4 inches on each side, probably constructed by one of the kings of Vientiane, is built on the former brick chedi. The oldest laterite structure, presumably may have had a hemispherical dome of the early Bud dhist stupa at Sanchi in northern India. Muang Boran reconstructed this monument in its actual size at 18 meters wide.
