Pivnice, Natural monument in Hluboká, Czech Republic.

Pivnice is a forested sandstone canyon between Zderaz and Dolany in the Chrudim district, covering 34.37 hectares. Pivnický potok carved the ravine, whose soft sandstone layers erode into overhangs, honeycomb weathering, evorsion potholes, pseudokarst niches and the rock tunnel Děravá skála. The narrow southeastern gorges are passable only over ladders set at waterfall steps of harder iron-rich sandstone.

Pivnice was declared a natural monument on 10 December 1998, protecting a canyon cut by the Pivnický potok into Cretaceous sandstones. The name's origin is uncertain; it may refer to the cool, damp air resembling a beer cellar, and a legend links the gorge to Hussite troops, hence the nickname Žižkovy maštale.

The name Pivnice likely comes from the cold, damp air in the canyon, said to resemble the temperature of beer cellars. A less-used nickname, Žižkovy maštale (Žižka's stables), comes from a legend that Hussite troops hid in the canyon.

The best time to visit is during warmer months when paths are drier and plant life is most visible. Wear sturdy shoes and bring water, as the terrain can be uneven in places.

The canyon's name likely comes from the cool, damp air between its walls, compared to the cellars where beer is chilled. A less-used nickname, Žižkovy maštale (Žižka's stables), comes from a legend that Hussite troops sheltered here.
