While we know Nepal's flag isn't a rectangle, most people assume all other flags are. However, Switzerland and Vatican City are the only two countries with square flags (a 1:1 ratio). All other national flags are rectangular. The Swiss flag, featuring a white cross on a red background, was adopted in 1841 and is one of the most recognizable symbols in the world. The square shape is a tradition that stems from its use as a military ensign in the Middle Ages. Interestingly, the Red Cross symbol—the inverse of the Swiss flag—was adopted to honor Switzerland's role in the Geneva Convention.
