.           At the time when Bangkok was first established, the ground was a rice field and was sometimes used as a location for a royal crematorium, Phra Men in Thai. The ground was, thus, otherwise called as Thung Phra Men which means the crematorium ground. In considering that the name was inauspicious, King Rama IV had the ground renamed as Thong Sanam Luang, or the Royal Ground, and the rice farming there cancelled. Later, King Rama V had the Wang Nas eastern wall demolished and the area of  Sanam Luang enlarged to cover a total of 78 rai as it does nowadays. The place has been used as the crematorium ground for kings, members of the royal family and nobility, in addition, to being a royal sporting ground. The king also had 365 tamarind trees planted around it.
