The municipal flag and the coat of arms from 1270 showed an eagle and a three-leaved linden tree with flowers. An illustration of the coat of arms in the Tschachtlan chronicle from 1470 does not contain the linden tree, but a red shield head can be seen above the eagle for the first time. The eagle owes its use as the heraldic animal of the city of Aarau to a folk etymological reinterpretation of the name as “Au des Aars”.

The first use of the city seal is on a certificate of the 25th. February 1311 testified. It showed, washed by spring water and surrounded by vines, a swimming pool in which a man and a woman sit and eat grapes. It was in use until 1497; in addition, there were six similar seals, which were used until about 1800. The hospital had its own seals (a hand in front of the Greek cross that extends two fingers). The first documentary mention of the Baden city banner dates back to 1361. The municipal regiment took it to the Battle of Sempach in 1386, the oldest pictorial representation can be found in the Tschachtlanchronik in 1470.

Its meaning is unknown but it is believed to come the Counts of Lenzburg or Austria. In 1441, the first representation of the banner in coat of arms, cast in iron, was placed above the gate of the city tower, with the exaggerated imperial eagle, which was to clarify the theoretical status as a Free Imperial City. The meaning of the coat of arms and the flag has not been handed down. It may be due to the Counts of Lenzburg-Baden, or it is a derivative of the red-white-red Austrian coat of arms. The coat of arms and the flag are still considered district coat of arms and flag. The colours are black and white.

The colours of the stripes comes from the flag of Austria.

The coat of arms and the flag, which has been held in Grub since the early 19th century, shows the green forest in blue. A black bear emerges from a cave in front of it. In order to bring the coat of arms and the flag closer into connection with coat of arms and flag laws as well as with its deeper meaning, the black circular symbol for pit was used. Since this is black, the bear had to be made yellow. This makes it different from those in other municipal coats of arms and flags in the canton.

The white wave represents the Linth river. The three yellow stars represents Ennenda, Netstal and Riedern while the black and white star represents Glarus. Both the coat of arms and the flag combines the symbols of all former municipalities.

The four stars to the left of the wave represents Bilten, Niederurnen, Oberurnen and Näfels while the four stars on the right represents of Mühlehorn, Obstalden, Filzbach and Mollis. The blue wave represents the Linth river. Yellow and blue is the traditional colours of the municipality.

The sunrays represents Mitlödi, Sool, Schwändi, Schwanden, Nidfurn, Haslen, Leuggelbach, Luchsingen, Hätzingen, Diesbach, Betschwanden, Rüti, Braunwald, Linthal, Engi, Matt and Elm. The white V-shaped wave symbolizes the confluence of the Linth and the Sernftal rivers. Blue stands for water which is a vital resource for the municipality.

The meaning of the letters were unknown. Interpretations suggest that they are either an abbreviation of the municipality, an acronym of "La Vera Giustizia Antica" or a symbol of a Roman legion. The cross on a red background alludes to both the symbols of Como in Italy and Switzerland.^[3][4][5]

The hemp plant represents the Canepas family (who are artists) and the crozier represents Bishop Enrico Silvio (1556–1612).^[6]
