From the nearby viewpoint you can see this monument, whose origin is surprising. 500 million years ago the entire area was covered by the sea, although with little depth, so it was filling with sands and clays brought by the rivers that flowed there from the Iberian plateau. It was 300 million years ago when the forces of the earth made these lands emerge and since then, the erosion of the river, the rains and the wind have been sculpting the relief, creating beautiful forms like these organs. On these rocks, holm oaks, cork oaks and scrub have found their substrate, forming a Mediterranean forest where genets, marten and numerous birds of prey live.
