Dívčí kámen, Medieval castle ruins near Holubov, Czech Republic

Burgruine Maidstein is a medieval castle ruin positioned on a rocky hilltop overlooking the Vltava River between České Budějovice and Český Krumlov in South Bohemia. The site displays stone foundations, walls, and structural remains that show the layout of this former fortified stronghold.

The fortress was founded in 1349 by the Rožmberk family under King Charles IV and served to control the river valley. Over the following centuries it was gradually abandoned and deteriorated into the ruins seen today.

The fortress served as a key residence for the Rožmberk family and held importance for the surrounding region. Today visitors can trace the family's presence through the building layout and architectural details that speak of their local influence.

The ruin is reachable by train to Třísov station or by parking in Holubov and following marked hiking trails to the site. Sturdy footwear is advisable since the paths are hilly and sometimes uneven.

The ruin measures 210 metres long and 45 metres wide, and its founding charter from 1349 survives, one of the few Bohemian castles with such a document. A red-marked trail passes the site between Boršov nad Vltavou and Zlatá Koruna, with a yellow trail leading to Holubov station.
