The national flag of Greece, popularly referred to as the “blue and white” (Greek: Γαλανόλευκη, Galanólefki) or the “sky blue and white” (Κυανόλευκη, Kyanólefki), is officially recognised by Greece as one of its national symbols and has nine equal horizontal stripes of blue alternating with white. There is a blue canton in the upper hoist-side corner bearing a white cross; the cross symbolises Eastern Orthodox Christianity, the established religion of the Greek people of Greece and Cyprus. The blazon of the flag is Azure, four bars Argent; on a canton of the field a Greek cross throughout of the second. The shade of blue used in the flag has varied throughout its history, from light blue to dark blue, the latter being increasingly used since the late 1960s. Zoom In. Full HD.
