The bat cave with the attached exhibition -Noctalis- is definitely worth a visit for young and old alike. The best time is in April, as some bats are still flying around in the cave. In summer, they have left their winter quarters and return in autumn. Please check the opening hours on the website.

Unfortunately, the now visible part of the Kalkberg is only a sad remnant of the once imposing hill, upon which once stood one of the few hilltop castles in Northern Germany. How different would the town's (tourist) development have been if there had been no intensive limestone mining and gypsum extraction, no Thingstätte (place of worship), and no Karl May Festival? A local historian and Hamburg's Hafencity University have undertaken a joint project on the Kalkberg and the Siegesburg castle on it, taking a virtual journey back in time to the era before both disappeared. A foretaste of the impressive result of this collaboration can be seen here: https://www.kreismuseum-segeberg.de/se1644/.
