The flag of Graubünden was adopted in 1933.
From 1815 to 1933, the canton had used various combinations of the three coats of arms of the historical Three Leagues. The modern design combines simplified versions of the historical coats of arms.
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.
