This attraction is situated close to the evangelical church where there is parking available. The Gapp Family have worked in Gosau for several generations as marble and stone grinders (the only business in the whole of Austria). Fossilised creatures up to about one million years old are found in river beds and certain rock faces around Gosau, and are cut and polished and turned into paperweights or ash trays by the Gapp family.
Visitors can also visit the exhibition of rare stones, fossils, objects they have lovingly and carefully made from their prehistoric "finds" and lots more. The exhibition is not only of geological interest. There is something there for everyone! Open daily. Admission is free.
