All forms of its names are derived from the medieval German word meaning "(the village on the) rich/resourceful mountain" (reicher Berg in modern German). The name was sometimes shortened to Richberk and Riberk, which gave rise to the Czech name Liberk. In Czech, words starting with "R" were often dissimilated into "L". The old street name Hablau near city centre is considered to be a trace of old village possibly founded by Havel of Lemberg, husband of Saint Zdislava of Lemberg
