Hrubá Skála (German: Groß Skal) is a municipality and village in Semily District in the Liberec Region of the Czech Republic.

In the southern part of the municipal territory flows the Jordánka brook, which supplies several ponds.

[3] The castle is situated on a steep sandstone cliff on a rock platform and was originally called Skála.

[4] Held by the Lords of Smiřice from 1515 onwards, the rebuilt Renaissance castle had become the centre of one of the largest Bohemian estates with more than 50 villages.

Seized by Emperor Ferdinand II upon the 1620 Battle of White Mountain, it was again held by the Waldstein dynasty from 1630 and devastated by both Saxon and Imperial troops during the Thirty Years' War.

[6] After World War II, the Aerenthal family was dispossessed in 1945 and the German-speaking population expelled according to the Beneš decrees.
