The Wat Traimit temple in Bangkok's Chinatown houses a three-metre-high Buddha made of over five tonnes of solid gold! In 1957, the stucco shell of a Buddha statue being moved by crane cracked to reveal a pure gold Buddha underneath.
Thought to have been fashioned in the 13th century, the gold Buddha (said to be worth upwards of £10 million in bullion alone) is a fine example of Sukhothai style, and its plaster covering is assumed to have been a (successful) attempt to disguise it from Burmese invaders.
