Swiss Flag - Official National Flag of Switzerland #281161 (License: Personal Use)

The Swiss flag consists of a white, upright equilateral cross in the center of a red square field, with a 2:3 ratio for the cross arms. Adopted officially in 1889, its design reflects centuries of Swiss tradition, military heraldry, and federal unity. Unlike most national flags, it is square-shaped-a rare distinction shared only with Vatican City.
