Wat Phra Si Sanphet in Ayutthaya

This is the most important temple within the Royal Palace compound (similar to the importance of The Emerald Buddha Temple in Bangkok's Grand Palace). In 1500 a 16-meters high standing Buddha was cast by King Ramathipodi II. The image was covered with gold weighing some 170 kilogrammes. In 1767, the burmese set fire to the image to melt off the gold, completely destroying the image and the temple.
Nearby are three ceylonese-style chedis built during the 15th century  to enshrine the ashes of three Ayutthayan kings. These were renovated in 1956.
