The Kozłowska Desert is an area of exposed sand dunes located in the Lower Silesian Voivodeship, within the Lower Silesian Forest, approximately 17 km southeast of Szprotawa. The formation of the Kozłowska Desert was influenced by the activities of a German, and later Soviet, military training ground, which operated until 1992, when the dune served as a shield for rockets and artillery shells. At that time, the bare areas of exposed sand covered over 100 hectares. After 1992, vegetation succession occurred, but a section of the desert is undergoing conservation efforts to preserve its existing terrain.

The Silesian Ramparts are the longest archaeological site in Poland. This medieval structure is considered the equivalent of the famous Great Wall of China. These are the until-recently-mysterious Silesian Ramparts, built in the 14th and 15th centuries on the border of the former Duchy of Głogów. The medieval Szprotawa District (districtus sprotaviensis) bordered the Duchy of Żagań to the west and the Duchy of Jawor to the south. The structure was enormous considering the local conditions. A system of ramparts and ditches was painstakingly constructed over several dozen kilometers, terminating at rivers or marshes. Sometimes the fortifications were so strong that they consisted of up to four adjacent ramparts. Hedges were planted and maintained on their crests to prevent sudden intrusions into the duchy. To give you an idea, at some sites the fortification system was over 40 meters wide with the height of the ramparts being about 2.5 meters!

Kozłowska Desert - an area of exposed sand dunes located in the Lower Silesian Voivodeship, in the Lower Silesian Forests, located approximately 17 km southeast of Szprotawa. The dunes in the Lower Silesian Forests are the product of aeolian processes, they were formed in the period after the end of the last ice age until they were covered with vegetation. The creation of the Kozłowska Desert was caused by the activity of a Soviet military training ground, operating until 1992, when the dune served as a shield for rockets and artillery shells.

Two interesting rocks are located in a beautiful hidden corner next to a small reservoir by a hydroelectric plant. Nearby there is a small observation deck overlooking the "lagoon" and the rocks.

Inspired by a trip to Asia, Friedrich Maximilian von Hochberg had the garden redesigned with several partial gardens. A Japanese garden with small watercourses and bridges between islets was laid out on an island in the Tschirne. From the castle to the west, the Chinese Garden extends as a further partial garden, bounded by two backdrop-like clinker walls on a curved floor plan with round and oval window openings, which are supposed to be reminiscent of Chinese moon gates. A path leads to the border of the garden, where a staircase and pagoda architecture crosses a street as a pedestrian bridge. Another area was the rose garden enclosed by an ornamental wall. From 1919 the von Alvensleben were the owners. Today the palace park has been extensively renovated. Source: Wikipedia
