*NOTE: TO VISIT THE CAVE, THE LAST VISIT IS ALWAYS HALF TIME BEFORE THE CLOSING TIME. FOR EXAMPLE, IF THE TIMETABLE IS FROM 10H30 TO 20H30, THE SALE OF TICKETS IS FROM 10H30 TO 20H00. AT 20H00, THE LAST GROUP TO VISIT THE CAVE WILL ENTER TO LEAVE AT 20H30 AS A MAXIMUM.
The Cave named “Cova del Rull” is discovered in 1919 by José Vicente Mengual (Uncle Rull) when he went hunting with his dog following a rabbit, he entered a hole, in which he also made a ferret enter for him to come out, not leaving any. The next day he tried to remove some of the stones from the hole and found the cave that bears his nickname.
In the Sixties, due to the rise of tourism, “Rull uncle” decides to open it to the public, conditioning the corridors a little bit.
It is currently owned by the City Council, and has been conditioned and open to the public since September the 16th of 1995.
Geological Setting of La Vall d’Ebo
From a geological point of view, the Ebo Valley is located in a region with such interesting problems that many professionals and specialists have long since won the attention. Its geological features correspond to the eastern prebetic branch, in the vicinity of the outermost edge with respect to the Alpine chain of folding south of the peninsula. The stratigraphy is varied and complex, spanning the stratigraphic column from the Triassic (Keuper) to the Quaternary. The Mesozoic materials are represented by a diapic Keuper and continuous sedimentation from the Dogger to the Senoniense. A second major sedimentary cycle of tertiary materials (Miocene) is arranged on this set. Finally, an extensive and low-power quaternary coating extends from the edge of the Mesozoic and Tertiary reliefs to the sea.
La Rova Cave has been developed in the Miocene conglomerates consisting of rounded limestone bowls and gravels that encompass a clayey-lime matrix and have a very variable calcareous foundation.
About 100 meters from the entrance of the cave, and going west along the road, a fault transverse to it, connects the conglomerates with the marshes in “Tap” facies. The massif is affected by subvertical and open diaclases. The cave owes its existence both to the solvent action of water on the calcareous components of the conglomerates, as well as to its drag action on the clay-clay matrix, to which the action must be added combined erosion and partial subsidence, usually localized.
The formation of the cave is also linked to other geological factors of a tectonic nature, such as the faults and the folds, which results in a fracture of the rock massif that allows the entry of water and its circulation inside the same . Slowly and slowly this flow of water has eroded and widened the fractures through which it has flowed. Under certain conditions of pressure and temperature, the infiltrated water has been able to dissolve the CO2 in the atmosphere or the existing one on the ground by bacterial action, constituting an acid that, although weak, attacks the calcium carbonate of the limestone rocks. (insoluble in water), transforming into calcium (soluble) calcium bicarbonate, which is dissolved and transported by water. A change in existing conditions can reverse this chemical reaction by depositing calcium carbonate in the form of stalactites and stalagmites and releasing CO2r again, which means that the cave growth process is only possible with continuous circulation of water. If circulation ceases, the development of the cave is limited to that produced by sinking.
Today, the Cave of the Rull is still one of the few caves in the Spanish east that is open to the public and they are still in the process of continuing formation.
