The flag of Chile, known as "La Estrella Solitaria" (The Lone Star), features two horizontal bands of white and red, with a blue square in the upper hoist corner containing a white five-pointed star. The white symbolizes the snow-covered Andes Mountains, the red represents the blood shed for independence, and the blue signifies the sky and the Pacific Ocean. The flag was officially adopted on October 18, 1817, and its design reflects Chile's natural beauty and the struggles for freedom. The star in the blue square stands for a guide toward progress and honor.
