Just a few facts about the Chedi: Phra Pathom Chedi is the tallest stupa in the world with the height of 127 metres (417 ft). A Stupa is a structure related to the Buddhist religion which contains holy relics. The temple which houses the stupa is Wat Phra Pathom Chedi located in the town of Nakhon Pathom, Thailand. The name Phra Pathommachedi (said in Thai of course) literally means “Holy chedi (stupa) of the beginning”. The stupa at the location is first mentioned in Buddhist scriptures of the year 675, however archaeological findings date back to the 4th century. In the 11th century it was overbuilt with a Khmer (Ancient Cambodia) style prang, which was later overgrown by the jungle. King Rama IV later rebuilt the chedi in its present glory, which was completed in 1870.
