Cornštejn Castle

Cornštejn Castle is a sprawling ruin perched on a high rocky promontory above the confluence of the Želetavka and Dyje rivers, within the cadastral area of Bítov, roughly 31 km west of Znojmo in south-west Moravia. Surrounded by forest and the waters of the Vranov Reservoir, it now ranks among the most scenic ruins in the region.

Where does the name come from and who built it?

The castle was raised in the 14th century on royal demesne land that had previously belonged to nearby Bítov Castle. In 1308 this territory was granted as a fief to the noble Lichtenburg family. It was Raimund of Lichtenburg, a favourite of King Wenceslaus II, who in the 1320s decided to strengthen the defences of Bítov and the road linking it to Vranov Castle by building a new stronghold. The name Cornštejn is thought to derive from a word meaning something like "sulky" or "truculent" castle, underlining its stern, defensive character.

How did the castle grow under the Lichtenburgs?

Raimund's sons, Smil and Čeněk, made Cornštejn their permanent seat and began styling themselves the Bítov Lords of Lichtenburg. The family gradually rebuilt and expanded not only Cornštejn but also Bítov and Vranov, weaving together a chain of fortified points that controlled the Dyje river valley. For decades the castle served as an important link in the region's defensive network.

What conflicts did the castle go through?

Cornštejn did not escape the turbulence of Moravian history. In 1422 it was besieged by Hussite troops, a sign of its strategic value during the Hussite Wars. A second siege followed in 1463, when the castle was taken by the forces of King George of Poděbrady. In the aftermath the king punished its owner, Hynek, and confiscated the property — an episode that closed a chapter in the stronghold's history.

Why did the castle fall into ruin?

Cornštejn gradually lost its military and residential importance and was finally abandoned in the 16th century. Left unoccupied, the building slowly deteriorated, leaving behind the extensive, atmospheric ruins that are today considered one of the most romantic spots in South Moravia.

What can visitors see on site?

The ruins are visited with a guide, who explains the stronghold's eventful past. In season, the site also hosts themed shows — jugglers, early music and swordsmen's performances — that evoke its medieval atmosphere. The biggest draw, however, remains the view itself: from the high promontory on which the castle stands, a wide panorama opens over the Vranov Reservoir and the surrounding forested landscape.

How do you get to Cornštejn Castle?

The castle lies within the cadastral area of Bítov, right next to the village and within easy reach of both Bítov Castle and Vranov nad Dyjí Chateau, making it easy to combine all three sights in a single trip through the Znojmo region. Because it sits on a rocky promontory, reaching the ruins involves a short walk on foot.
