The Siebentäler Therme in Bad Herrenalb was planned in 1971 by architect Karl Heinz Angst from Tübingen. Nestled in the landscape between the park Schweizer Wiese and the Falkenstein at the entrance to Bad Herrenalb, the architectural design of the thermal baths marks the transition from a classical bathing establishment to a modern recreational spa. After more than 50 years of operation, the thermal bath now needs to be renovated. In order to adapt the facility to current needs, the technical and design aspects are being revised by 4a Architekten.
