A rather sinister myth surrounds Phra That Kong Khao Noi , a brick-and-stucco chedi dating from the late Ayuthaya period found along Hwy 23, 5km out of town towards Ubon.

The farmer, eating his lunch over his mother’s dead body, realised that the small basket actually contained more sticky rice than he could manage to eat. To atone for his misdeed, he built this chedi .
