PP Pustý zámek

Pustý zámek is a natural and historical landmark in the Czech Republic, located three kilometers east of the town of České Kamenice, in the northern part of the Česká Lípa district. Rising to 405 meters above sea level over the valley of the Kamenice river, the hill combines two distinct features: a rare geological formation and the ruins of a medieval castle.

A rock face shaped by the river

The site's main draw is a steep basalt rock face roughly 50 meters high, carved out over thousands of years by the erosive force of the Kamenice river. The wall is built from massive, four- and six-sided basalt columns up to 25 meters long and 1.85 meters thick. Near the base the columns lie almost horizontally, but they tilt increasingly upward higher on the slope, forming a distinctive fan-shaped pattern in solid rock. Part of the formation was disturbed in the 19th century during road construction, though this did not diminish the value of what remains.

Castle ruins on the hilltop

At the top of the hill stand the remains of Fredevald castle. It was most likely built by the Michalovice family before the end of the 13th century, with the purpose of guarding a trade route that ran through the Kamenice valley toward Žitava, on the other side of the border. Only fragments of the original structure survive today, but the location itself — perched on the edge of the rock face, overlooking the valley — makes the site's medieval strategic importance easy to appreciate.

Nature protection

Because of the uniqueness of the rock formation, the area was granted legal protection on July 4, 1956, by decision of the then Ministry of Education and Culture. The protected area covers 1.99 hectares and lies on the southern slope of the hill, at an elevation between 350 and 380 meters. It is managed by the Nature and Landscape Protection Agency of the Czech Republic, Liberec regional office. Pustý zámek forms part of the larger Lužické hory (Lusatian Mountains) Protected Landscape Area, known for numerous rock formations shaped by the region's volcanic and erosional history.

Why visit

This is a place where nature and history meet in a striking way. Geology enthusiasts will appreciate the rare arrangement of basalt columns, clearly visible thanks to the steep, exposed face of the rock. Those drawn to history will find a tangible trace of medieval defensive settlement — the ruins of a castle that for centuries watched over a cross-border trade route. Combining both elements within a relatively small area makes Pustý zámek a worthwhile stop for anyone exploring the Lužické hory region, especially alongside a visit to the nearby town of České Kamenice.
