Jelenia Góra Valley (Polish: Kotlina Jeleniogórska; Silesian: Kotlina Lelýniohorski; German: Hirschberger Tal; Literally "Deer Mountain Valley") in Poland is a big valley at the Silesian northern side of the Western Sudetes and next to Kłodzko Valley the largest intermontane basin of the Sudetes. It is situated at an altitude of 250–400 meters above sea level and covers an area of 273 km2. In the 19th century, the lovely landscape attracted the Prussian high nobility, which built magnificent palaces, manors and parks. The enormous number of stately homes turned the valley into one of the most important garden landscapes in Middle Europe.
