The Stone Mountains (; ) are a mountain range in the Central Sudetes, lying mainly in south-western Poland and partly extending into the Czech Republic. The highest summit is Waligóra (936 m). The Krucze Mountains form the eastern part of the range.
The Stone Mountains are surrounded by the following mountain ranges and regions: to the northeast, the Waà Âbrzych Mountains; to the east, the Wà Âodzickie Hills; to the south, the Nowa Ruda Depression and the Stoà Âowe Mountains; and to the west, the Broumov Highlands.
The Stone Mountains extend south of Waà Âbrzych and along the PolishâÂÂCzech border. Their relief is among the most rugged in the Central Sudetes, with steep slopes, narrow valleys and sharply defined ridges.
The Krucze Mountains form the eastern part of the Stone Mountains and are therefore part of the range rather than a separate mountain system.
The central and highest part of the range is protected within the Sudety Waà Âbrzyskie Landscape Park, which includes Pasmo Lesistej and the western part of the Suche Mountains with Waligóra.
During World War II, Nazi Germany operated subcamps of the Gross-Rosen concentration camp in Bernartice, MezimÃÂstÃÂ, Kamienna Góra, Lubawka and Mieroszów, in which over 3,500 people were held as forced labour.
