The Ślęża (Polish: [ˈɕlɛ̃ʐa]; German: Zobten or Zobtenberg, later also Siling) is a 718 m (2,356 ft) high mountain in the Sudeten Foreland in Poland.

Ślęża is located in the territory of Sobótka in Lower Silesian Voivodeship in southern Poland, about 30 km (19 mi) southeast of Wrocław.

During the Neolithic Period and at least as far back as the 7th century BC Mount Ślęża was a holy place of the Pagan tribes of the Lusatian culture.

The Silingi, a subpopulation of the East Germanic tribe known as the Vandals are the earliest inhabitants of Silesia known by their name, however the greater part of them moved westwards after the 5th century AD and the remainder were slowly replaced in the 6th century by Slavic tribes who assimilated the few remaining East Germanic inhabitants.

[4] In the first half of the 12th century, the owner of the place was the Polish dukes' governor, Piotr Włostowic, who founded there an Augustinian convent which was subsequently moved to Wrocław in 1153.
