Beginning of Petrified Wood Preservation is from King Rama VI. He came to Ban Ta Kut Khon, Tha Chang subdistrict, Chaloem Phra Kiat district, Nakhon Ratchasima in order to inspect the railway tracks construction, the bridge is being built across the Mun river. 

       Before he back, Phraya Ramphaiphong Boriphat (Mr. Jit Bunnak), the chief engineer, offered him with the Petrified Wood that villagers brought up from the bottom of the Mun River, when in the drought.

       However, the king gave it back to the villager and suggestion to preserve it in local area. So, Phraya Ramphaiphong Boriphat made a petrified wood monument at the foot of a railway bridge over the Mun River which remains until today. So, Thailand has been preserved petrified wood for nearly 100 years.
