Hor Phra Keo means Image of the Emerald Buddha. It was so named because it once housed a precious emerald Buddha that was taken to Bangkok in 1778. The temple was built in the 16th century by King Setthathirath (reigned 1547–1571) of Lan Xang as a royal temple. It was destroyed during wartime in 1828. In 1936 King Sisavangvong (reigned 1904–1959) ordered the reconstruction of the temple. The reconstruction was completed in 1942 and it was later converted to a national museum for housing numerous religious artifacts.
The main hall is built on a double-layer base platform forming two sets of verandas. It has a hip-and-gable roof with five overlapping sections and triple-tier eaves.
