The old town of Česká Lípa was built near a ford by the Ploučnice River where a Slavonic colony existed from the 10th century. The line of the Ronovci and Jindřich z Lipé in particular contributed to the founding of the city between 1305 and 1319, and the line of the Berkové z Dubé promoted its development. A hundred years later the city was occupited by the Hussite army of Jan Roháč z Dubé and devastated by fires. Albert of Valdštejn, and later Kaunitzs, contributed to another boom of the city by founding a monastery and school. The modern urban development of the city was influenced by industrial production and uranium mining in the region. Residential neighborhoods consisting of prefab housing in large were built on the outskirts while the city center was preserved and enunciated as an urban heritage zone.
