The castle was founded by King Wenceslas IV as a strategic base for his hunting trips in the Posázaví region.
In the mid-15th century, the castle became a notorious stronghold for the predatory knight Jan Křinecký, who used it to raid surrounding trade routes.
The name 'Zbořený Kostelec' translates literally to 'Destroyed Church' or 'Demolished Castle'.
The 1449 siege was conducted by the Landfried, an alliance of Bohemian nobility aimed at suppressing banditry.
After its destruction, the castle was never rebuilt, leaving the ruins in a state of 'controlled decay' for over 500 years.
Castle Zbořený Kostelec is a ruined 14th-century fortress situated on a rocky promontory overlooking the confluence of the Sázava and Vltava rivers. King Wenceslas IV commissioned the original structure around 1341, serving as a significant defensive point in the region. The castle was famously captured and destroyed by royal troops in 1449 to end the activities of the robber knight Jan Křinecký z Ronova. Today, only fragmented stone walls, vaulted cellars, and segments of the inner curtain wall remain of the original Gothic complex. The site is currently managed as a protected archaeological site and historical landmark. Visitors access the ruins via a steep forest path through the surrounding woodland. The strategic position allows for extensive views over the Sázava river valley. Archaeological excavations at the site have provided insights into medieval military architecture and living conditions. The site remains largely unmaintained, preserving a raw, ruinous aesthetic.

Visit during dry weather; the limestone paths and rocky terrain become hazardous after rainfall.
Do not attempt to reach the ruins in low-light conditions or heavy rain, as the unmarked forest trails are prone to erosion.
Do not climb on the loose masonry or marked walls to prevent further structural degradation and personal injury.
