There are few different versions of stories about origin of Luang Phor Sothorn. There were 3 Buddhas brothers statues which floated along northern river to Bang Pakong river area in reversed drift. Local people saw them and tied ropes on the hands of statues. About 500 of them helped to pull the statues ashore but their efforts were in vain. The rope was cut off and the three statues dropped under the water and disappeared. The 3 Buddha statues then floated along Bang Pakong river until the south of Wat Sothorn but weren't pulled ashore and were kept floating in reversed drift.
