History of the Menzenschwand radon cure

and the development of the thermal springs of St. Blasien-Menzenschwand

The idea

The idea of using radon-containing water in Menzenschwand for therapeutic purposes dates back to 1970.

It was not until 1970 that radon-containing water with a radon content of 1130 Bq/l was discovered in the Krunkelbach valley, which was drilled into the granite. This medicinal water formed the basis for the radon spa project, which was valued at the time at around 75 million euros. In addition to the spa with a health resort, large hotel complexes were to be built. The plans eventually failed because the citizens, the municipality and the investors did not agree on the size and scope of the project.

Almost thirty years later, the idea of the radon spa was taken up again. In 1998, the St. Blasien town council, in collaboration with the citizens, developed a model that allows any interested party to participate directly in the project in the form of an "association". With these associates, it was achieved that the new radon spa was not only desired but also "supported" by the population, both financially and psychologically.

With total funding of EUR 6 104 000, citizens have so far contributed EUR 640 000.

The spa and its architecture

Freiburger Stadtbau GmbH, in cooperation with the Freiburg architectural office Detlef Sacker, was awarded first prize for its innovative design in a European architectural competition and also won the contract for the construction of the spa.

The building is divided into three areas:

 In the centre of the bath is the bathing area with a hot water pool, whirlpool and adjacent rest areas. The outdoor swimming pool is accessible via an airlock. The bath has a total area of 240 square meters of water. The transparent entrance area with service, surveillance, catering and cashier is located in front of the pool.

 In the east wing of the building there are therapy rooms and baths for physiotherapy and radon therapy. In the west wing there is a wellness area with various sauna cabins and relaxation rooms. The attractively designed garden, which is directly accessible from the saunas, has an outdoor sauna and a graduation building.

 Due to the height of the building and the smooth transitions between the interior and exterior, the complex blends harmoniously into nature without the need for major landscaping measures.

 Bath and sauna guests have the possibility to switch from the inside to the outside of the building. The indoor swimming pool and sauna area extend to the outside and offer a breath-taking view of the landscape. Sunbathing and relaxing on the terrace are not only possible in summer but also in winter, as the dark stone of the terrace heat and thus creates a pleasant atmosphere even after sunset or without direct sunlight.

 In the outdoor bathing area, a barefoot path for extraordinary sensory experiences has been created in the heath, which has been largely left in its natural state. The path also offers visual stimulation through sculptures in the green area of the resort. In a hushed atmosphere, visitors can enjoy the view of the Alb valley, which blends in with the rest of the landscape, and forget everyday life.
