Baden, mineral springs, Inhalatorium and 150 years of Kursaal

2 February 2026

After conquering what is now Switzerland in 13 BC, the Romans quickly discovered the mineral springs at Aquae Helvetica, now known as Baden (canton of Aargau). Geneva had already been conquered in 120 BC, and Nyon (Colonia Julia Equestris) and Augst/Kaiseraugst (Colonia Augusta Raurica) had been Roman towns since 44 BC. Still, Baden was the first town to have Roman baths (thermae).

Although the departure of the Romans was detrimental to the culture of Roman baths, the mineral springs continued to operate. In the Middle Ages, this culture experienced a renaissance, and the healing effects of this mineral water became increasingly well known.

In the 19th century, public baths and the use of mineral springs were gradually replaced by private establishments for the bourgeoisie and the nobility. Grand hotels, tasting halls, thermal fountains and other spas were built in Baden and along the Limmat.

The highlight was the opening of the Kursaal in 1875. This complex was a casino, concert hall, dance hall and, above all, a meeting place for Swiss and international high society.

This history of Baden as an internationally renowned spa resort is presented in words and pictures in the former Inhalatorium on the Limmat promenade until 15 March 2026.

In addition, guided tours of the town will take place on 21 February and 7 March, focusing on the mineral springs, spas, (former) grand hotels and the Kursaal. The Inhalatorium, which also has its own story to tell, is the meeting point.

Registration is through the Baden History Museum (Historisches Museum Baden), which is organising the exhibition “Mittendrin im Vergnügen. Kursaal-Stadtsaal-Stadtcasino” until 5 July 2026.
