The plants that cover the upper part of the towers help with this. The calcareous water then runs down the outside of the tower. The water evaporates, the lime precipitates and builds up the spectacular dripstone balconies.” “The process is as follows: 1) At the beginning, the towers are not yet overgrown. Rain washes out the stone. Below, the sea water erodes the stone. 2) The plant growth produces acid, which accelerates the decomposition of the rock. The dissolved limestone runs down with the water. In the lower part of the towers, dripstones are formed. 3) The dripstones grow into mighty columns that can even reach the ground or the sea. Unanswered questions: The water washes out many caves on the outside, but these disappear after a few metres into narrow crevices. The question is wh...
