Three towers of Angkor Wat appear on Cambodia’s current national flag. The white temple is centered on the flag’s broad red stripe, between narrower blue bands.
The three-towered image is a stylized emblem rather than a complete architectural drawing. The real Angkor Wat has five central towers arranged in a quincunx, representing the five peaks of Mount Meru in Hindu cosmology. The flag’s simplified view shows three prominent towers, which makes the design recognizable at a distance.
Angkor Wat has appeared on Cambodian flags in some form since the late 19th century. The present blue-red-blue design was first adopted in 1948 and readopted on September 24, 1993, after the restoration of Cambodia’s monarchy. Red traditionally represents the nation, while blue is associated with the king.
The number five is therefore a tempting but incorrect answer for this question: five describes the temple’s central towers, while three describes the towers drawn on the modern flag. Cambodia is one of the few national flags to feature a building.
