Kelheimer Auerkalk

Kelheimer Auerkalk use dates back to the roman empire and can be seen again during the gothic ages. Since the 18 century, Kelheimer Auerkalk had spread itself far outside its Bavarian borders, as can be seen in the Stephan's cathedral in Vienna.

The stone originates from coral reefs of the Jurassic sea over 150 million years ago. It was created by the mixture of debris from reefs and coral branches in which sedimentary limestone manifested itself and eventually solidified creating a compact limestone.  It is especially suited for claddings and flooring as well as mass construction.
