The Kößlerhäusl is the oldest house in the Grossarl Valley.
The cottage housed the Kößler family, who originally earned their money as chaste farmers. In times of need they had to help themselves as small farmers. The floor of the log cabin is made of rammed clay and the furnishings are limited to the bare necessities. The house consists of a small stable, a smokehouse and 2 small rooms on the upper floor.
