Subsequent to more than 2 months of exploration and archaeological excavation of the Lieu Coc Twin Towers monument, the experts judged that there are 2 main tower temples in the monument, with no sign of a third tower temple. If so, then the Lieu Coc Twin Towers monument is a special and sole monument in the system of Champa Tower temple monuments with 2 main worship towers.

After a period of phase 2 excavation of the Mount Ban relic, experts have discovered many more layers of foundation, sandstone, broken bricks... From these discoveries, it can be determined that the altar of heaven in Mount Ban in the Tay Son period had a simple construction technique, taking advantage of the natural rocky terrain.
