In La Vall de Gallinera, there are at least two great rocks with a hole, both on the southern slope: the one that gives its name to the mountain range and the one discovered in Benirrama by F. Vilaplana, probably known in ancient times but completely forgotten today.

Another possible tunnel presents more particular characteristics. It is the cave known as Cova Obrada or Cova del Moro, which is accessed from inside a pen on the crest of the mountain, where a hole opens that leads to a cave open towards the valley and walled off centuries ago. Although the entrance to the cave has its entire surface chipped, its origin may have been a small fissure.

Cova Obrada del Moro is a unique building due to the questions it raises regarding its origin and functionality. The proximity to the Tower of Penya Foradada (a 13th century construction) suggests that they could have been related and that it could have been used as a complementary or temporary prison since it is a place that offers guarantees to prevent the escape of captives. In this sense, a case is known, studied by Josep Torró in Llibre de la Cort del Justícia de Cocentaina (Book of the Court of Justice of Cocentaina), in which Guillem de Sèrvoles, from Cocentaina, accuses Domingo Navarro of not having fulfilled the task of carrying a message to his father, a captive in the Foradada rock, after the revolt led by Al-Azraq in April 1276.
