Sanam Luang is a big field in front of Wat Phra Kaew and the Grand Palace in Bangkok, Thailand. Sanam Luang has another name, Tung Pra Me'ru (meaning cremation field). It was used for cremation of the King and his royal relatives. In 1855, King Rama IV changed the field's name to Sanam luang, announcing that the old name was thought unlucky.
