The field was officially renamed from Thung Phra Men to Sanam Luang in 1899 by King Rama V.
During the early Rattanakosin period, the area was utilized for royal cremation ceremonies for the King and members of the royal family.
The site hosts the annual Royal Ploughing Ceremony, which marks the traditional start of the rice-planting season in Thailand.
More than 300 tamarind trees surround the field, many of which are over 100 years old.
The ground was used as a landing strip for small aircraft during the 1920s.
Sanam Luang serves as a significant landmark for the geographic center of the Rattanakosin Island district.
Sanam Luang is a historic, oval-shaped open field located in the heart of Bangkok's historic district, historically known as Thung Phra Men. It serves as the primary ceremonial ground for Thai royal cremations and significant national events, including the Royal Ploughing Ceremony. The square is bordered by the Grand Palace to the south and the National Museum of Thailand to the west. Originally used as a rice field, it was converted into a royal ceremonial site during the reign of King Rama I. The perimeter is lined with mature tamarind trees planted during the reign of King Rama V. Throughout the 20th century, it functioned as a public park and a weekend market site before restrictions were increased to preserve its historical integrity. It is currently managed by the Bureau of the Royal Household.
