Mitterbad was once one of Tyrol's most popular and visited spa towns thanks to its mineral springs which contain iron and magnesium. The water was used for drinking cures and bathing. Poorer visitors used bathtubs made of wood, whilst the more exalted guests bathed in marble baths. Mitterbad's heyday was during the 19th century, continuing until 1919. Otto von Bismarck, Empress Elisabeth of Austria, the writer brothers Thomas and Heinrich Mann and the painter Franz Defregger were only some of the many personalities who paid a visit to Mitterbad.
