Cosmas of Prague
The settlement was first mentioned in the "Chronica Boemorum", written in 1119–1125 by Cosmas of Prague. A Benedictine monastery with the Church of the Blessed Virgin Mary was founded here probably at the end of the 11th century. It was built near the site where a former Slavic gord called "Drahúš" on the Ohře river had been erected at the behest of the Přemyslid dukes. The monastery's premises were devastated during the Hussite Wars in 1420 and not rebuilt.
