Jáchymov (Czech pronunciation: ; German: Thal originally, later Sankt Joachimsthal or Joachimsthal: "Saint Joachim's Valley") is a spa town in north-west Bohemia in the Czech Republic belonging to the Karlovy Vary Region. It is situated at an altitude of 733 m (2,405 ft) above sea level in the eponymous St. Joachim's valley in the Ore Mountains, close to the border to Germany.

The silver Joachimsthaler coins minted there since the 16th century became known as Thaler for short, with the word "dollar" and similar words for monetary units in many languages deriving from it.

History, mining and coinage

Silver mining in Jáchymov (1548)

At the beginning of the 16th century, metallurgical studies on his observations made here.

In 1523, the Protestant Reformation began. In the Schmalkaldic War (1546–47) Joachimsthal was occupied for a time by Saxon troops. When in 1621 the Counter-reformation and re-Catholicisation took effect in the town, many Protestant citizens and people from the mountains migrated to nearby Saxony.

Until 1918, the town (named Joachimsthal before 1898) was in the Austrian part of the Dual Monarchy of Austria-Hungary, head of the district with the same name, one of the 94 Bezirkshauptmannschaften in Bohemia.[1]

In the 19th century the town was also the location of a Court, and of an administrative office responsible for mines and iron production. Mining was still significant in this period. It was run partly by state-owned and partly by privately owned firms. In addition to silver ore (of which in 1885 227 zentners [11.35 tonnes] were produced), nickel, bismuth and uranium ore were also extracted. There were also other industries: an enormous tobacco factory employed 1,000 women. In addition, there was the manufacture of gloves and corks and of bobbin lace.

On 31 March 1873 the town almost entirely burnt down.

At the beginning of the 20th century, Marie Curie discovered, in tons of pitchblende ore containing uraninite from Joachimsthal, the element radium, for which she won the Nobel Prize in Chemistry. Until the First World War this was the only known source of radium in the world.

The first radon spa in the world was founded in Joachimsthal in 1906, joining the famous spas of the region, like Karlsbad, Franzensbad, Marienbad.

In 1929, Dr Löwy of Prague established that 'mysterious emanations' in the mine led to a form of cancer. Ventilation and watering measures were introduced, miners were given higher pay and longer vacations, but death rates remained high.[2]

In 1938, it was annexed by Germany as one of the municipalities in Sudetenland. The German-speaking population was expelled in 1945 (see the Beneš decrees) and replaced by Czech settlers.

Modern town

After the Communist party took control of Czechoslovakia in 1948, large prison camps were established in the town and around it. Opponents of the new regime were forced to mine uranium ore under very harsh conditions: the average life expectancy in Jáchymov at this period was 42 years.

Uranium mining ceased in 1964. The radioactive thermal springs which arise in the former uranium mine are used under the supervision of doctors for the treatment of patients with nervous and rheumatic disorders. They make use of the constantly produced radioactive gas radon (222Rn) dissolved in the water, see Radon therapy.

Nearby attractions

Not far from here, at the foot of the Plešivec, there once stood the Capuchin monastery Mariasorg (Mariánská); it was razed to the ground in the 1950s.

From the valley of the Veseřice a chairlift goes to the highest peak in the Ore Mountains, the 1244 m high Klínovec.
