While wellness holidays are a relatively new trend, saunas and baths have been around since the 7th century AD. In the 12th and 13th centuries AD, Medieval bath houses would always feature saunas. Castel Rundegg was built around that time but back then it of course bore very little resemblance to the wonderful Beauty Hotel it is today. Saunas, however, already looked pretty much like they do today, with various benches at different heights.
It was for fear of epidemics and plagues that most saunas then disappeared until the late 17th and early 18th century AD, when many private and public saunas and baths were established yet again. They were mostly used for cures and to treat illnesses, making them early precursors of today’s wellness oases and spas, such as the ones that can be found in the Merano health resort.
