Many coastal poles were planted in the beach. They give the beach a beautiful stamp. They are there to stabilize the dunes and the coast and to protect them from erosion. The poles help to maintain the dune structure and prevent them from being washed away by the wind and the water. They play an important role in the preservation of the natural environment and the protection of the coastal areas.
