Státní okresní archiv Chomutov se sídlem v Kadani

The present archive was created by the merger of the Chomutov and Kadaň District Archives in accordance with the changes in the territorial division in 1960. Its predecessors were the Chomutov District Archives and the Kadaň District Archives. However, the origins of archiving are much older here. The oldest list of documents kept at Chomutov town hall dates back to 1727, in Kadan there is evidence of the newly established archive in the town hall from 1755. Archives in the present sense of the word originated in the districts of Chomutov and Kadaň only on the basis of the government decree of 7 May 1954 as facilities of District People's Committees. In July 1960, the Chomutov and Kadaň district archives were merged into the Chomutov District Archives, based in Kadan, in the building of the former Franciscan monastery (from XIX century till 1960 the premises of the District Court) . In 2002, it became part of the State Regional Archives in Litoměřice.
