Grillenburg Sandstone

There used to be a number of sandstone quarries in the Tharandt Forest and its neighbourhood, not far from Höckendorf (Paulsdorf Heath) and Ruppendorf, near Grillenburg, Niederschöna and Hetzdorf in the state of Saxony.

These Cretaceous sandstones emerged in the Cenomanian and Turonian ages.

This sandstone is both fine- and coarse-grained; its colour ranging from white to brown; in addition to quartz and mica, numerous plant impressions of the genus Credneria are found in it.

According to sedimentological investigations and historical research, the material for the Golden Gate of Freiberg Cathedral came from the "ashlar stratum" (Werksteinbank) in the area of Grillenburg.
