The Enchanted City is a Spanish natural setting of calcareous or limestone rock formations formed over thousands of years. It is located near Valdecabras, in the municipality of Cuenca (Spain), in a wide area of pine forests in the southern part of the Cuenca mountains and at an altitude of 1500 meters.

It was declared a Natural Site of National Interest on June 11, 1929.

The action of water, wind and ice has made this karst phenomenon possible.

The heterogeneity of the rocks in terms of their morphology, chemical composition and degree of hardness is what has allowed their uneven wear by atmospheric elements, resulting in a surprising sample of picturesque art from nature itself. To the capricious and spectacular existing formations we must add slopes, torcas and sinkholes.

The rock formations of the Enchanted City are karst patterned formations, whose origin dates back to the Cretaceous period, approximately 90 million years ago. In the Cretaceous, the Sea of ​​Thetis covered much of what is now the Iberian Peninsula and the area that today makes up the Enchanted City was part of the background. It was an area of calm waters where there was a significant deposition of salts, mainly calcium carbonate, from the skeletons of the animals in the area and from the portion dissolved in the water.

At the end of the Cretaceous, the alpine orogeny originated the elevation of the land, part of the surface that was previously seabed became part of the emerged land. The calcium carbonate banks converted into limestone were exposed to atmospheric agents, such as rain, temperature changes, and biological agents, such as the action of different living beings, which were progressively eroding the rock. Limestone rock is very permeable and allows infiltration of rainwater. The water, together with the action of carbon dioxide (CO2), dissolves the limestone rock, increasing its porosity even more and forming galleries inside it, resulting in karst formations.

The Enchanted City is a very advanced karst where much of the rock has been dissolved, most of the galleries have collapsed when the roof of the caves fell and only the blocks of the most resistant stone areas remain standing. by the erosion capricious forms.
