Semická hůra, Summit in Central Bohemia, Czech Republic

Semická hůra rises around 231 meters (760 feet) above the Polabská lowlands, forming a distinct table-shaped peak composed of sandy siltstone. The hill reveals layers of Czech Cretaceous Basin materials when explored from different angles.

Archaeological finds on the summit reveal settlement traces from multiple periods, including the Lusatian, Knovíz, and Silesian cultures. These discoveries show that people were drawn to this location repeatedly over thousands of years.

The name Polabské hůry links Semická hůra with Přerovská and Břístevská hůra, three table hills of the Elbe lowland. The southern slope, protected since 5 October 2009 on the proposal of environment minister Ladislav Miko, preserves white-slope grassland with red-list species such as Aster linosyris, Gentianopsis ciliata and Stipa joannis.

Semická hůra lies southwest of the village of Semice, reachable on foot from the surrounding lanes; no marked trailhead or visitor facilities exist. The southern slope is a protected Natura 2000 locality, so stay on existing paths. The summit hillfort is unexcavated, and the terrain is steepest from the north.

The summit holds an unexcavated hillfort from the Celtic and early Slavic periods, never dug up, so its ground plan is not yet known. The southern slope was added to the Natura 2000 list on 5 October 2009 on the proposal of environment minister Ladislav Miko, under the name Polabské hůry.
