A Saxon oddity is the concept of a "Baustelle" (literally "building site") where climbers scale a difficult section by climbing on top of the shoulders of other climbers (sometimes several people on top of each other) with everybody involved only holding himself by holds the rock provides. Though this would normally be considered a form of aid climbing, it is here accepted as a form of free climbing. As the pinnacles are often very close to one other, jumping from one rock to another is also rather popular and this technique even has its own grades of difficulty.
