The museum in the manor houses many treasures - including a black tourmaline from his native climes. The crystal shawl was made by honorary citizen and mayor aD Manfred Kienzle secured the construction of the Sommerberg tunnel in 1991. The former Hausacher Rathauschef is a hobby general and had at the time the miners at the beginning of the construction of the summer mountain tunnel in July 1991 asked to pay attention to possible special finds. That was a great wish in the speedy work. Because Kienzle would have been added only a few minutes later - the magnificent chunk would now be embedded in a dam. But the luck was the collector hold. The ingrown Turmalinkristalle - the black variety is called Schörl - arrange radially radial to a 'sun'. They are up to 56 cm long and up to 3 cm wide. The step comes from the western tunnel area, about 50 meters from the mouth hole. Prof. Gregor Markl from the University of Tübingen speaks of a rare piece, probably the largest find to date in Europe.
