Wat Phra Pathonnachedi Wora Viharn

Phra Prathon Chedi (pronounced [pʰráʔ prā.tʰōːn t͡ɕēː.dīː]) is one of the oldest stupas in Thailand with the height of 50 metres (164 ft). The stupa is located in the Wat Phra Prathon Chedi Wora Viharn, a temple in Nakhon Pathom, Thailand, 3 km east of Phra Pathommachedi. The name Phra Prathon Chedi means the holy stupa of Thona or Thanan, name of an ancient measurement. According to legend after the cremation of Gautama Buddha, his relics were equally divided amongst 8 royal families and his disciples by using a golden Thona. This golden Thona eventually sent to ancient Nakhon Chai Si in Suvarnabhumi and kept inside a stone stupa in 590. King of Sri Lanka wanted the golden Thona, so he sent a prominent monk to ask the golden Thona from the King of Nakhon Chai Si. The king agreed in exchange of one Thona of holy relics of Buddha and built a new stupa to keep the holy relics, which is Phra Pathommachedi. In 656 King of Lavo ruled Nakhon Chai Si and rebuilt the stupa and named Phra Prathon Chedi.
