Ralsko Military Training Area

The area is about 250 square kilometres (97 sq mi) consisting of forests, meadows and sandstone rock formations.

From 1914, the Graeflich Waldstein Forestry Office operated a narrow-gauge forest railway between Rečkov and Kummer, which was used to transport lumber.

The area also created an ecologically valuable landscape in which many endangered animal and plant species live.

Some of the villages and towns in the area have recovered since the closure of the military zone and the pullout of Soviet troops, such as Hvězdov (Höflitz), Kuřívody (Hühnerwasser), Noviny pod Ralskem (Neuland am Rollberge), Stráž pod Ralskem (Wartenberg am Rollberg), Okna (Woken) and Cetenov (Zetten).

Other small villages remain in ruins (pieces of foundations or walls) or have completely disappeared, such as Černá Novina (Schwarzwald), Holičky (Hultschken), Horní Krupá (Kridai), Jablonec (Gablonz), Olšina (Wolschen), Palohlavy (Halbehaupt), Proseč (Proschwitz), Svébořice (Schwabitz), Strážov (Straßdorf) and Židlov (Schiedel).
