Since around 1850, the Cambodian flag has featured a depiction of Angkor Wat in the center. The flag used today is the same as that established in 1948, although since then 5 other designs have been used. These have almost all made use of the image of the temple of Angkor Wat in one form or another. This famous temple site, which dates from the 12th century, was built by the Mahidharapura monarchs. It has 5 towers, but these were not always all depicted in the stylized version used on flags.
Khmer text reads 'Kingdom of Cambodia' and the motto 'Nation, Religion, King'.
