The national flag of Chile, also known as la estrella solitaria (Spanish for "the lone star"), consists of two equal horizontal bands of white (top) and red and a blue square the same height as the white band at the hoist-side end of the white band, which bears a white five-pointed star in the center. It was adopted on October 18, 1817.
The star represents a guide to progress and honor; blue symbolizes the sky and the Pacific Ocean, white is for the snow-covered Andes, and red stands for the blood spilled to achieve independence.
