Evidence points to a settlement as early as the Bronze Age and Hallstatt period. The Illyrians and Celts settled here, like the Romans. Then Bavarians settled and mingled with the population. The first mention of the name "Prugg im Pinzgrey" occurred in the year 1227. Since the completion of the Grossglockner High Alpine Road in 1935, the city has been called "Bruck an der Großglocknerstraße" ("Bridge at the Grossglockner road"). In 1938, the independent village of Sankt Georgen ("St. Georgen") was amalgamated.
After the Second World War, in Bruck's efforts to create a separate community stepped up arms again, there was a new draft, which was included in the former official seal of the municipality. This seal had included the then-unofficial emblem Eismadonna (iron madonna) as a coat of arms. Considering the fact that several communities in the region of Pinzgau, from a long time ago, had also used the Madonna's heraldic symbol, it had been discouraged by this kind of arms design.
As provided in the following years, but again the link with the town's name of the bridge over the river, a crook was added to the former seal, symbolizing the close association with the Lord on Fischhorn Castle, the Bishop of Chiemsee. This kind of presentation of a herald was welcomed with little enthusiasm.
After long deliberation, it was decided then at least to a so-called speaking of arms, which was created by Prof. Mag Gerd Nowotny and then from the Salzburg provincial government on 17 September 1976, the town was also awarded: the coat of arms shows, in a silver shield, a three-peaked green mountain, with a silver bridge, in front, crossing along a river.
It is expressed therefore, in the coat of arms, as the bridge over the Salzach River, the name of the place and the connection with St. George brought about by the Three Brothers symbolized expression.
