Jachymov Spa with its unique natural healing resources and a specific spa programme has an important role in West Bohemian balneology.
The former mining town is situated in the foothills of the Krusne Hory Mountains at an altitude of 560 - 750 metres above sea level in a region with the largest occurrence of minerals in the world. There are 250 different types of minerals to be found here. The Svornost mine forms an important part of the spa as it is here that the healing radon water is collected and distributed to balneology establishments in the town.
The Svornost mine was founded at the same time as the town. The town has enjoyed the status of a free mining town since 1520. During the course of the 16th century the mine was used mostly for mining silver, and later on for mining other non-ferrous metals. Since the mid 19th century the main mineral mined here was pitchstone, firstly used for the production of uranic paints and later for the production of radium and from1946 it was used as a source of atomic energy.
Jachymov is the only radon spa in the Czech Republic and its waters have the highest healing radon activity per litre in the whole world.
