Castellfollit de la Roca is a unique village in Spain situated atop a basalt crag that is over 50 meters (160 feet) high and nearly a kilometer long. This geological formation gives the village a spectacular setting, perched dramatically on the edge of the cliff. The crag itself is a result of volcanic activity, forming part of the Garrotxa volcanic zone in Catalonia, Spain. Castellfollit de la Roca is not only notable for its stunning natural surroundings but also for its historical and cultural significance, offering visitors a glimpse into both geological history and traditional Catalan life.
