The flag of Liechtenstein (German: Flagge Liechtensteins) is the national flag of the Principality of Liechtenstein. It consists of two horizontal blue and red bands charged with a gold crown in the canton. The colors and symbols of the flag carry cultural, political, and regional meanings. The blue represents the sky, while red alludes to the “evening fires” that are lit inside houses throughout the country. The crown – whose colour is disputed – epitomizes the “unity of the people and their prince. While The World Factbook and Reuters describe it as gold in colour, other sources – such as Whitney Smith in the Encyclopædia Britannica – describe it as yellow.The flag is best used indoors but can withstand occasional outdoor use. The authentic design is based on information from official sources.
