“Gassen” was first mentioned in a document in 1406; the first settlers in the valley were the Slavs. The first church, dedicated to St. Oswald and St. Barbara, was built in the 13th century. In the heyday of mining, from the 16th to the 18th century, gold, arsenic, silver and magnetic ironstone were mined in the municipality. Several scythe forges along the Gasenbach stream were in operation until the end of the 19th century. Today, Gasen is a typical mountain farming village with extremely steep slopes.

Gasen lies on the border of the district of Weiz and borders on the district of Bruck-Mürzzuschlag. Gasen consists of the districts of Gasen, Sonnleitberg, Mitterbach and Amassegg and lies between the municipalities of Breitenau and Birkfeld.

Gasen is mainly used for agriculture and forestry and is considered the steepest mountain farming village in Styria.
