The flag of Greece is based on nine equal horizontal stripes of blue alternating with white.

There is a blue square in the upper hoist, called canton containing a white cross.

The cross symbolizes Greek Orthodoxy, the traditional religion of the country, and each of the nine lists corresponds to a syllable of the phrase "Liberty or Death".

The official proportions of the flag are 2:3.

The color scheme of blue and white was first used in the 1820s, but the current form was not adopted as the national flag in 1978.

Previously, a darker blue, the flag was only used at sea and the merchant marine, and the national flag was a simple white cross on blue background.
