Wat Ratchaburana was built upon a sad story of brothers fighting against each other. It was built by the order of King Borom Rachathirat II (Chao Sam Phraya) on the ground site where his two brothers, Chao Ai Phraya and Chao Yi Phraya were fighting for a throne after their father died and both finally died during a combat on elephant’s back. The two main pagodas were then stored precious matters, Buddha images and royal possessions which are now displayed at Chao Sam Phraya National Museum.
