This natural arch was collected by the author during a 10 days hiking trip along Costa de Cantabria between the town of Ribadescella and the village of Celorio in september 2014. On this gallery, the arches are shows from east to west. Nice karstic rock pinnacles formation (lapiaz) are predominant on this section of the coast. This arch is fully surrounded by these limestone formation. This attractive opening look like has an old medieval defence bristling with pikes.
