Rajadamnern Stadium

Rajadamnern Stadium is the oldest Muay Thai stadium in Thailand, located on Ratchadamnoen Nok Road in Pom Prap Sattru Phai District, Bangkok. Opened on 23 December 1945, it was the first purpose-built stadium for Muay Thai in the country. The venue hosts professional Muay Thai bouts several evenings per week and is recognized as a historic center for the sport, featuring a standard boxing ring, tiered seating and traditional ceremonies.

Visitors can expect an indoor arena centered on a raised boxing ring surrounded by tiered seating including ringside, second and third class sections. On event evenings, multiple Muay Thai bouts are held with traditional live music, Wai Kru Ram Muay ceremonies before fights, and announcements in Thai and English. The building retains mid-20th century architecture with covered stands, lighting for evening events, and concourse areas with food, beverage and souvenir vendors.

Commissioned by Prime Minister Field Marshal Plaek Phibunsongkhram and opened on 23 December 1945, Rajadamnern Stadium was the first stadium in Thailand built specifically for Muay Thai. Construction began during World War II and was completed after the war. It established standardized rules, weight divisions and a stadium championship system that shaped modern Muay Thai.

Rajadamnern Stadium is regarded as one of the two most important Muay Thai stadiums in Thailand alongside Lumpinee Stadium. It preserves traditional elements of Muay Thai including the Wai Kru Ram Muay, Mongkol and live traditional music, and its championship belts are among the most prestigious titles in the sport.
