In the very west of the Czech Republic, at the state border with Germany, is the Ostrovsko region, which comprises 14 separate municipalities:

Abertamy, Boží Dar, Hájek, Horní Blatná, Hroznětín, Jáchymov, Krásný Les, Merklín, Ostrov, Pernink, Potůčky, Stráž nad Ohří, Velichov and Vojkovice.

It is an area that offers visitors a wide range of attractions. For nature lovers, hikers and fans of summer and winter sports and recreation – a number of trails, phenomena and sites such as the highest peak of the Ore Mountains, Klínovec (1244 m above sea level) and the highest town in Central Europe, Boží Dar (1028 m above sea level) with its peat bog. Furthermore, the Blatná moat, the nearby Vlčí jámy sinkhole with cave ice, the Celní skála (Customs Rock) and the 70 m long trail carved in the rock in Stráž nad Ohří, etc. In winter, there are kilometres of groomed cross-country skiing trails and ski slopes and cableways in the mountain resorts of Abertamy, Pernink, Boží Dar, Horní Blatná, Jáchymov, Loučná pod Klínovcem.

The Ostrovsko and Poohří region seemed to be a favourable place in the distant past. And so the Slavs (Velichov) noticed its advantages and chose it for their fortresses. Later on, various historical milestones did not avoid the region. This is evidenced by many monuments, whether they are buildings and castles in Ostrov, Velichov, Šlikova Tower in Jáchymov, Hauenštejn near Krásný Les and Himlštejn near Stráž nad Ohří. Landscape monuments include the Island Chateau Park, known as the Eighth Wonder of the World in the Baroque period, and the Hornohrad Park.

The area has always been a place where different cultures have clashed, with a predominantly German, but also Jewish element, as evidenced by one of the oldest Jewish cemeteries in the country in Hroznětín. The German environment in particular suffered greatly after 1945 with the displacement of the original population. The locality is famous for several attractions and also for its well-known mining and mining activities. Thus, the area between Pernink, Horní Blatná (also tin mining) and Abertamy (glove making) was called the “silver triangle” and Jáchymov is also very famous for its mining activities, as well as its coin minting, the discovery of radium by the Curies, the spa industry and the infamous uranium camps of the 1950s. The museums in Horní Blatná, Jáchymov and Boží Dar are a proof of the past glory.
