Etymology The name "Krupka" was derived from an Old-Czech word krupý, which approximately means "large". Geography Krupka is located about north of Teplice and east of Ústí nad Labem. The southern part of the municipal territory with the built-up area lies the Most Basin, the northern part lies in the Ore Mountains. On the southern border of Krupka there is the Kateřina Reservoir, built at the beginning of the 20th century. It was built as part of water management protection, and today it is also used for recreational purposes. History The origin of the original mining town is connected with the mining of tin ore and its further processing. The first written mention of Krupka is from 1305 in a deed of King Wenceslaus II. In 1330, existence of a guard fortress is mentioned. After the Hussite Wars, Krupka gained town privileges. In the 17th century, problems with mining activities began to appear, and tin sales were stuck. The Thirty Years' War adversely affected mining. In 1708, the Clary-Aldringen family purchased the Krupka manor, and owned it until 1918. In the 19th century, the economic centre moved to neighbouring Bohosudov with the establishment of new factories and lignite mines. In 1858, the railroad to Bohosudov was built. In 1898, Bohosudov was promoted to a town. From 1938 to 1945, Krupka was one of the municipalities in Sudetenland. In 1960, Bohosudov was merged with Krupka and became its most populated town part.
