The Gorges of Dobrudja do not resemble the keys that we used in the Carpathians, whether they are smaller or larger. The valley here is wide, meandered, and the limestone walls are quite a distance from the water. The height of the walls is not high, 30-40 meters, but the keys here have something special, a unique attraction you can not find in the Carpathians. The limestones here are reefs, which preserve the traces of the former atolls in the form of ruinous relief. The atolls formed in the warm warmth that covered the Jurassic and Cretaceous area of Dobrogea (Thetis Sea - 180-100 million years ago) are still visible in the walls of the gorges. The scaffolds of coral colonies, deposited in more or less circular shapes, can be seen very well over the entire length of the keys. Palms, horseshoes, pyramids, towers, recognize them immediately if you have used your eye and you know what to look for. In the central area of the keys, a rectangular tower is well kept. It looks like a cooling tower from a miniaturized thermal power plant ... and it has deposits of sediment covered with grass inside.
