Siebengebirge

The Siebengebirge is a German low mountain range consisting of more than 40 mountains and hills. It is located south-east of Bonn on the right bank of the Rhine in the vicinity of the cities of Königswinter and Bad Honnef in the state of North Rhine-Westphalia. The origin of the mountains is of volcanic origin. It is home to the state`s largest contiguous nature reserve.

The economic use of quarries and mining can be traced back to Roman times.
From 1875 mining came to a standstill for economic reasons. From 1930 the quarry activities were stopped for nature conservation reasons.
