Coat of arms Grossarl got its coat of arms in 1965. It is a green uprooted
alder on white ground. The illustration of the alder accords to the old German name of the market town "Arla". In 1339, Grossarl was mentioned as the valley with "merern Arel", what means "many alders". The sign of the alder shows the big tree clearings in the valley from the 11th to the 13th century. It also shows the big meaning of the wood industry in the valley. Some people say that it is also a symbol for the attachment of the inhabitants to the valley and its leaves show many children which were born in Grossarl. == Economy and infrastructure ==
