The Emerald Buddha's exact origin is unknown. Legends and myths continue to surround this mysterious icon, Thailand's most sacred Buddha image. Official records claim the Emerald Buddha was discovered in 1434 at Wat Phra Kaeo in the Chiang Rai province. A bolt of lightning struck a pagoda, revealing a small and seemingly insignificant stucco Buddha image. The plaster began to crumble away, revealing a beautiful green jade Buddha. When the King of Chiang Mai heard of the discovery, he sent an army of elephants to take the Emerald Buddha. But the elephant carrying the treasure refused to take the route back to Chiang Mai, and instead headed south towards Lampang. The Emerald Buddha eventually came to Wat Phra Kaew, Grand Palace, Bangkok, Thailand. Three times per year, His Majesty the King of Thailand changes the robes of the 66cm Emerald Buddha. The robes, made of gold and diamonds, signify the changing of the seasons, summer, winter and monsoon. A crown and jewelry in the hot season; a golden shawl in winter; and a gilt robe and headdress in the rains.
