Located in the middle of a rice field, about one kilometer away from the village of Mueang Pang in the Umpachan sub-district of Pakkachak Sinlapakhom District, Udon Thani Province, lies a hill known as "Nai Dong Lau" adorned with a large number of white champaka trees, commonly referred to as "Lantom." This area, once a dense forest, was revered by local villagers, believed to be a sacred site. On significant religious days, residents often reported seeing bright lights emanating from this hill. The elevation, coupled with the discovery of old bricks and a discernible arrangement of bricks underneath the surface, led to the belief that this location was originally a stupa. The mound was likely formed from the collapse of the stupa after many years. Later, the area was established as a temple named Wat Non That. The first abbot was Phra Kru Udom Jetiya Phinun (Nukoon Pasato), who constructed a stupa that housed numerous sacred relics, Buddha statues, and the relics of noble disciples, serving as a place of worship for both deities and people. Today, the white champaka trees within the temple have been officially recognized as a national heritage under the patronage of His Majesty King Maha Vajiralongkorn Bodindradebayavarangkun, as of July 15, 2018, by the Ministry of Culture.
