The Kalkberg (Limestone Mountain), 91m asl., does not consist of limestone, but is the gypsum cap of a salt diapir. It is the only hill composed of hard rock in Schleswig-Holstein, all other hills are moraines and consist of sand and rubbles. So the people some centuries ago did not know the difference between limestone and gypsum, they thought this was limestone as they saw it was white. And as this is the only hill composed of hard rocks, it also contains the only caves of Schleswig-Holstein, the Segeberger Kalkhöhlen.
The salt diapir is very close to the surface and dissolved by groundwater. The gypsum is less soluble than salt and so it accumulates at the top. But there is still a lot of salt, which is the reason for the many salt water springs in this area. This brine, with an extremely high amount of 26,74% salt one of the strongest in Germany, is the reason why Segeberg received the title Bad (spa) in 1925. In 1884 the first bathing house was constructed, to exploit the healing powers of the brine baths againts gout, rheumatism and sciatica.
The rock was used as a quarry for many centuries until between 1934 and 1937 the Nazis built a Thingplatz inside. This is a half German, half Nordic word meaning gathering place, one of many they used to garnish their "philosophy". A Thingplatz was simply an open air theater, which was used for political festivals.
Today the open air theater is used to show adaptions of the stories of Karl May. Karl May was an 19th century German author, who wrote adventure stories about remote areas of the world he had never seen. It was a sort of early pulp fiction, but it was extremly popular over more than a century. This popularity boosted during the 1960s when German movies after his books became popular too. The Karl-May-Spiele (Karl May Games) are a sort of theater event with actors from the movies.
