The Vogtland's highest mountain is Schneehübel, reaching 974 metres; another remarkable landmark is the Schneckenstein, 883 m above sea level, which gained some renown for its (falsely) alleged unique abundance of topaz crystals.Those settlers arrived mainly in eleventh and twelfth centuries, ethnically being Slavic or German, coming from areas of traditionally older settlement [de] like Franconia, Thuringia and Saxony.Even today this can be traced along lines dividing dialectal areas, providing linguistic differences at close distances of settlement while demonstrating peculiar commonalities with varieties spoken in more distant regions of Germany.Among the privileges of the Vogts were the endowment over minerals still unextracted from the ground (Bergregal) and the entitlement to regulating mint and coinage affairs (Münzregal), which were both handed down to them by Kaiser Frederick II in 1232.As in the 14th century claims to power by the Margraves of Meissen emerged, Henry of Plauen submitted to the tenure-based regnancy of the Bohemian Crown, excepting only the dominion of Voigtsberg, that stayed tenured to the Reich.In 1357 an exchange of territories was agreed with by the Margraviate of Meissen, effectually making Wiedersberg, Liebau, Adorf, Pausa, Neuenkirchen and Hirschberg (among others) Meissenian while Borna, Geithein and Kohren were handed to the Vogt.Bohemian King George of Podiebrad took the burning of the royal castle of Graslitz due to fights between Henry II of Plauen and his enemies to be an occasion to withdraw his tenure and have the Vogtland occupied by Ernest in 1466.
