The flag of Switzerland is instantly recognizable due to its distinctive square shape, unique among sovereign state flags (except for the Vatican City). It features a bold, free-standing white equilateral cross centered on a striking red field. Its origins are deeply rooted in Swiss history, evolving from military banners used by the Old Swiss Confederacy, particularly linked to the canton of Schwyz.
While variations existed for centuries, the precise dimensions of the white cross on the red field were formally established in 1889. This iconic red and white cross design is globally associated with Switzerland and symbolizes neutrality, democracy, peace, and protection. Notably, the emblem of the International Committee of the Red Cross, founded in Geneva, deliberately uses the Swiss flag's colors inverted (a red cross on a white field) to honor the nation's role.
