Vestiges of a period of war, the southern coast of the Iberian Peninsula is full of these combat constructions, from the civil war of the last century, small fort with thick walls, space provided for shooting. These abandoned panopticons on cliffs and beaches, like dirty camera obscura made of stone, a past machine gun nest. On the opposite of firearms, these panoramic shooting are projected through the three rectangular bunker's pinholes, not to the exterior but inside.
