Panský lom, Natural monument in Liberec, Czech Republic.

Panský lom is a natural monument south of Liberec, west of Pilínkov, beneath the Hlubocký ridge and Černý vrch. In the former quarry's dolomitic limestone lies the fissure cave Hanychovská, a winter roost for bats. The protected area is managed by the Liberec Region.

Panský lom is a natural monument, ev. no. 2320, south of Liberec in the Liberec District, west of the Pilínkov city district beneath the Hlubocký hřeben ridge and Černý vrch of the Ještěd–Kozákov range. The protected area is administered by the Nature and Landscape Protection Agency of the Czech Republic; the Liberec Region issued the regulation establishing it.

The former quarry's fissure cave, called Hanychovská, is the reason the site is protected: it serves as a winter roost for bats. Among the species recorded there are the greater mouse-eared bat (Myotis myotis) and the lesser horseshoe bat (Rhinolophus hipposideros).

The monument lies west of the Pilínkov district, below the Hlubocký hřeben ridge and Černý vrch in the Ještědsko-kozákovský hřbet. The Hanychovská fissure cave in the former dolomite limestone quarry is a bat wintering site, so entry is not a visitor route; observe the quarry walls and slopes from outside.

The cave is named Hanychovská after the Hanych family, who owned the quarry. Besides the greater mouse-eared bat and lesser horseshoe bat, the winter counts also record Brandt's bat and the pond bat, described in the Slovak source as the rarest bat of northern Europe.
