The museum rooms, some of which have been preserved in the size of the former bathing cabins, tell the 800-year history of the former imperial village of Soden, which became Nassau in 1803 and Prussian in 1866. The salty healing springs, which still bubble up in the park today, once made salt extraction (until 1812) and the spa (1701-2001) possible.

With the Hessian territorial reform in 1977, the once independent rural communities of Altenhain and Neuenhain were also incorporated into Bad Soden am Taunus, which has officially borne the title Bad in its name since 1922 and has had town rights since 1947.

Pre- and early history & geological profile Pre- and early historical finds are presented in an original museum cabinet from 1910: Not only did the Romans pay a visit to the Soden healing springs, but finds from the Neolithic and Celtic periods have also been made here.

Salt extraction Salt has been boiled in Soden since the Middle Ages, and since the 17th century with the help of two graduation buildings designed to increase the brine content.

Famous spa guests In the 300 years of the spa industry, many famous people came to Soden, especially in the 19th century, such as the composer Felix Mendelssohn Bartholdy or the writers Heinrich Hoffmann, Friedrich Stoltze and Leo Tolstoy. The room is also adorned with an original wooden bathtub from the 1950s from the baths.
