Wat Ratchaburana was erected by King Boromracha II (1424-48) in memory of his elder brothers Ay and Yi, killed in a duel over the succession to the throne. Columns and walls of the wiharn still stand, as do some ruined chedis around the prang and also parts of the surrounding walls complete with lancet gateways. The large prang with its fine figured stucco, portraying nagas supporting garudas, is exceptionally well preserved.
