Ummendorfer sandstone
The Ummendorfer sandstone , also called Magdeburg sandstone , was mined not far from the village Ummendorf in the district of Börde in Saxony-Anhalt (Germany). This sandstone is historically significant because, on the instructions of Frederick the Great, a large part of these sandstones was used for his magnificent buildings in Potsdam and Berlin .
Occurrence and rock description
The sandstones that were broken west of Magdeburg to the neighboring Braunschweig area were also known as Magdeburg sandstone. This sandstone was formed in the Lower Lias . It is a mica-bearing fine-grained sandstone with a clay-containing bond, which is colored light gray to light yellow. It has low strength values, which is why many historical buildings made of this natural stone show strong signs of weathering. The layers are thick and in the vicinity of Ummendorf this stone was also quarried in Seehausen and Wefensleben .
Buildings
Well-known buildings that were built from Ummendorfer sandstone are the Sanssouci Palace in Potsdam and the Magdeburg Cathedral . Other buildings are the Pauluskirche in Magdeburg and the Ummendorf Castle .
