Drachenfels

The Drachenfels is a slope 321 meters 1,053 ft in the Siebengebirge uplands among Konigswinter and Bad Honnef in Germany. The slope was framed by rising magma that couldn't get through to the surface, and after that cooled and wound up strong underneath. It is the subject of much the travel industry and sentimentalism in the North Rhine-Westphalia region. The demolished manor Burg Drachenfels, on the summit of the slope, was worked somewhere in the range of 1138 and 1167 by Archbishop Arnold I of Cologne and bears a similar name.

It was initially proposed for the insurance of the Cologne area from any strike from the south. Initially it comprised of a bergfried with court, sanctuary and living quarters for workers. The chateau was insulted in 1634, amid the Thirty Years' War, by the Protestant Swedes and never remade. As a vital resource it had outlasted its value. Disintegration because of the kept quarrying undermined a great part of the remaining parts and just a little part is left today. The stone, similar to the remainder of the Siebengebirge, is framed by the leftovers of a fountain of liquid magma and has been the site of a trachyte quarry since Roman occasions, which, among others, conveyed the structure material for the Cologne Cathedral.
