Artillery Bunkers V-SY with Tunnels

Artillery bunkers of a rare type — gun emplacements made of monolithic concrete with stepped canopies. They are connected by tunnels running through the hill, and from the outermost bunker there is a passage leading to a storage room. From the outside, the bunkers are strikingly overgrown with agave and cacti. Access is nearly unrestricted, though you will need to climb up the slope from the road.
