The mining town of Horní Blatná is one of the most picturesque examples of the mining towns planned and constructed in the Renaissance style on greenfield in the Erzgebirge. In contrast to many mining towns, which were built following the discovery of significant silver ore deposits, Horní Blatná is the only example of a planned town connected to the discovery of tin deposits. It was founded in 1532 by Johann Friedrich, the elector of Saxony at the time. Like Marienberg in Saxony, the town has a central, almost-square market place and a system of perpendicular streets. Furthermore, there are a number of valuable historical buildings of Gothic or Renaissance architecture, as well as a series of more recent half-timbered buildings in the vernacular style of the 18th century. In 1992, the historic centre of Horní Blatná was declared a protected urban area.
