In olden times the Rhine flowed into a deep mighty lake above the town of KÖnigswinter. Those who then lived near the Eifel Mountains or on the heights of the Westerwald, were in constant fear of these swelling waters which often overflowed, causing great destruction in the country. They began to consider that some great saviour was necessary, and sent a messenger into the country of the Giants, begging some of them to come down and bore through the mountain, which prevented the waters from flowing onward. They would receive valuable presents as a recompense.

So one day seven giants arrived in their country bringing enormous spades with them, and with a few good strokes of their tools, they made a gap in the mountain so that in a few days the water washed through the gap which visibly became larger. At last the river streamed through in torrents. The lake gradually dried up and completely disappeared, and the liberated Rhine flowed majestically towards the plain.

The Giants looked at their work with satisfaction. The grateful folk brought them rich treasures, which they had taken out of the mines. Having divided them fraternally, the Giants shouldered their spades and went their way. These heaps of rocky ground which they had dug out were so great, that ever since they have been called the Seven Mountains, and will remain there until the Giants come again and sweep them away.
