Silver mining
On 23 February 1654 in Annaburg, the founding of Johanngeorgenstadt at the Fastenberg right on the border in the "Amt" of Schwarzenberg by Bohemian Protestant refugees driven from Horní Blatná was approved by Elector John George I of Saxony. By 1680, there were roughly 100 ore mines in the town and the surrounding area. Silver mining also branched into tin mining, reaching its high point about 1715 and declining during the 18th century.
