Aargau (Argovia) is the ancient name of the march between Alemannia and Burgundy, but it never was an independent canton historically. Since 1712, the territory of the modern canton had been divided between Zürich and Bern. The canton of Aargau was created as an administrative division of the Helvetic Republic, and its flag is an original design by Samuel Ringier-Seelmatter, dating to 1803.
The current official design, specifying the stars as five-pointed, dates to 1930.
Most mass-produced flags are commonly 150x90cm / 5x3' or 90x60cm / 3x2', which will often vary from the official size ratio. We now offer a custom-manufactured official size option for our many of our flags.
