The village of Radelstein was first mentioned in the year 1390. In this year King Wenzel of Bohemia established the Kladrau Cloister and purchased the village. The cloister pledged a festival to Buschek of Rozwora, but as of 1556 was still lien property. Lieutenant Urbar, of the Army of Bischofteinitz-Zetschowitz said that as of 1587 the village consisted of five farms. The names of the owners of these farms, Marschalek and Dusky, were still present in these villages as of 1945. Under the rule of Zeschewitz, Radelstein became a entailed estate of Bischofteinitz, which incorporated 93 villlages. The community became a political district of Mies during the First World War. In 1789, the historian Schaller traced the remains of a destroyed church, and two fallen castles. The city became known for their two grease burning ovens, which were transported to Saxony, Rheinland Pfalz, Bavaria, and Donau. This invention was remembered in a festival called “Schmierenstieg”, which celebrates the connection between Tscharlowitz and Nemlowitz. In 1839, a tar oven was used, but only by the upper classes. In 1869 steampower arriven in Radelstein and with it, came the turpentine factory. The community of Radelstein, belonged to an extended area of the forest that was the property of the Prince of Trauttmannsdorf. The Forester who maintained the area was under the supervision of the Heger in Gottschau bei Kladrau, in Hudelmühle, St. Barbara and Trubitz.
