It is believed that this Buddha image was made in the 15th century, but it ended up in Bangkok on 1782 after several wars. The robe of the Buddha image is changed 3 times a year by the King himself. During the hot season, the image has a diamond encrusted gold robe, while a solid gold robe is reserved for the Emerald Buddha in the cold season.
Since this is the most important temple in Thailand, there are several signs around the entrance that notify visitors about the dress code. Wearing sleeveless shirts, shorts, and open ended shoes is not permitted, but long trousers are available for loan for those who forget.
