the site dates from between the 1st and 3rd century a.d in 1559 the original chedi was replaced with a taller lao-style one, built as a demonstration of faith by king jayachettha of chantaburi (modern day wiang chan or vientiane,in laos)as he spread his capital south across the mekong river. For many years the monument had leaned to one side because of subsidence and finally collapsed in 1970. Restoration of the chedi by the fine arts Department was completed in 1977
