Žermanický lom, Natural monument in Žermanice, Czech Republic

Žermanický lom is a former two-hectare quarry cut into a body of těšínite, a volcanic rock similar to basalt, near the northeastern end of the Žermanice dam. Its south-facing sunlit wall and water-filled floor now form a wetland of pools and marsh plants.

The site was officially designated as a protected natural monument in 1992 to preserve its ecological importance for the Moravian-Silesian region. This protection established formal safeguards for the specialized plant habitats and geological features found here.

The quarry's Czech name, Žermanický lom, ties it to the village of Žermanice; the site lies by the northeastern end of the Žermanice dam, built in the 1950s with stone taken from here. The south-facing quarry wall warms in the sun, and rainwater collects on the floor in pools and small wetlands.

The quarry has no marked trails; a former access track leads down to the bottom and becomes a stream in wet periods. The floor is flooded in spring and dries out in summer, and mud washed from fields above can make it boggy. The site lies near the northeastern end of the Žermanice dam.

The quarry was cut into těšínite, a volcanic rock similar to basalt, not limestone. Its south-facing wall warms quickly and, together with rain-fed pools on the floor, supports a population of the dark darter dragonfly (Sympetrum danae), one of 19 dragonfly species recorded here.
