The Haze Cave is unique in Germany. It is located on the site of a former quarry where red sandstone was extracted in the 17th century. Quarry workers noticed a "haze" at a certain depth that caused people to faint. Dead birds were repeatedly found in the pit. Well doctor Dr. Johann Philipp Seip came to Pyrmont in 1712 and investigated the phenomenon. He suspected it was sulfur vapor. Carbon dioxide (CO2) was only discovered a few years later as atmospheric acid. The metal half-shells symbolize the numerous springs in Bad Pyrmont.

History Count Friedrich VI of Spiegelberg, who had been sovereign of the County of Pyrmont since 1525, built a fortress with a residential building on top in the valley of Pyrmont between 1526 and 1536. As early as 1512, he had the ancestral seat of the Counts of Spiegelberg in Coppenbrügge converted into a contemporary fortress based on the Italian model. He used the experience he gained to build a fortress in Pyrmont as well. The almost square complex covered four and a half hectares and was surrounded by a 30 to 40 meter wide moat, a moat. The earth that accrued when digging the moat was piled up to build the castle wall with casemates incorporated into it. In the north, where the fortress was most vulnerable to attack, a small stone corner bastion was built. The entrance to the fortress was only accessible via a wooden drawbridge and the entrance tunnel was.

Directly adjacent to the spa park is the Bad Pyrmont moated castle (or vice versa?!) The castle, which still exists today, dates back to the 18th century and was the summer residence of the Counts of Waldeck-Pyrmont.

The café in the castle courtyard is not as busy during the week, so you can better enjoy the view of the park.
