Königgrätzer Sandstein

ochre-yellow sandstone

honed

Occurring on the banks of the River Elbe, “Königgrätzer Sandstein” is a highly versatile material that can be used for a multitude of purposes and is prized for its warm hues, colour transitions and textures. This attractive sandstone blends gracefully into its surroundings and is highly compatible with many of the iconic buildings that give historical town centres their distinctive character. This is demonstrated beautifully by many historical townscapes. The Podhorni quarry has been in operation for several centuries and is still one of the most productive quarries in Bohemia/Czech Republic for yellow fine-grained sandstone.

This “Königgrätzer Sandstein” is a highly sustainable building material.
