The ancients used it for indicating the position of the sun, important for religious rites and agricultural seasons.

To get there, take the Sakon Nakhon-Udon Thani road for 22 kilometres and take a road on the left for 14 kilometres, then ascend 491 steps. The laterite pagoda is on a square base, seemingly unfinished because it has no roof or pagoda top.
