Hradisko svatého Klimenta, Archaeological site and national cultural monument in Osvětimany, Czech Republic.

This medieval fortified settlement sits atop a 461-meter hill in the Chřiby Mountains, surrounded by forests and offering commanding views of the surrounding Moravian countryside.

A fortified Slavic settlement with a permanent farming community stood here in the first half of the 9th century. After Great Moravia's fall it served as a refuge stronghold; pottery finds document occupation into the 10th and early 11th centuries. It lay abandoned by the first half of the 12th century, and Brno Augustinians built a Gothic church beside the old 9th-century chapel after 1358; it stood until 1421.

The location remains an active pilgrimage destination where annual religious celebrations take place during Pentecost, continuing centuries-old traditions that connect local communities with their spiritual heritage.

Visitors can access the site via roads from Osvětimany and Koryčany villages, approximately five kilometers southeast of Koryčany, with parking available and walking paths leading to the ruins.

The site is locally called Klimentek, and a folk legend recorded around 1700 by chronicler Jan Jiří Středovský links it to 864, when Cyril is said to have begun building a church here to hide Saint Clement's relics from wartime danger.
