The first documentary reference to Nenndorf as "Neues Dorf", which means 'new village', dates back to the 10th century. Later, from the middle of the 16th century, the existing sulphur springs were discovered by the rural population and used for medicinal purposes. But it was Landgrave Wilhelm IX. of Hesse-Kassel, who made Nenndorf a mud bath and sulphur spa, erecting a number of buildings there. In the 19th and 20th centuries, further buildings were added, for example, the Esplanade Hotel and the Spa Theatre.

Visit Bad Nenndorf's gorgeous Spa Garden, which was created in the early 19th century in the style of the English landscape garden, but also includes a sun garden and a beautiful promenade. A distinctive feature of the Spa Garden is the avenue of dwarf or twisted beech trees ('Süntelbuchen'), which are labelled after the Süntel, a massif in the German Central Uplands; they are rare specimens of the European or copper beech with conspicuously twisted and contorted branches. They were planted there at the beginning of the 20th century.
In the Spa Garden you should also visit the Small Palace, which was erected as the summer residence of the landgrave and future Elector Wilhelm I. of Hesse. Today the Small Palace accommodates a café.

Actually the so-called Spring Crater at the edge of Bad Nenndorf is not a crater, but a ring wall of tuff around a pond which holds saturated lime water from a nearby Deister river. As soon as it comes into contact with the air, lime is secreted which forms a limestone deposit on the verge of the pond, similar to a volcanic crater. This natural monument already gave visitors in the 19th century the idea of  making flower arrangements sink in the pond, where they kept their fresh looks for a number of months. Nowadays many spa guests throw coins into the pond, hoping for a speedy recovery.

The waterworks is a piece of art created by the renowned artist Timm Ulrichs. It deals with a typical  everyday issue: the daily washing-up, which even today is not always done by a dishwasher. The crockery is made out of aluminium. Since it was erected in 2016, this work of art has stirred up a lively controversy in Bad Nenndorf.
