Wat Rajaburana (or, Ratchaburana) was founded in 1424 by King Boromaraja II, as a dedication to his two fratricidal brothers, who died in battle while fighting each other over the throne. The Khmer-style prang (tower) was built after the king had captured Angkor Thom. A substantial treasure, found underneath, is now in the Ayutthaya museum.
