There are literally thousands of precast concrete bunkers everywhere, little half-buried domes with one or two gun ports, in clusters of three or four. This mountain could have held off the Normandy invasion, if it had somehow managed to sail landing craft 50 km inland and up a cliff.
I explored a few bunker complexes, and am now sitting at the edge of a cliff, staring down at the city far below.
There is no sound but the wind humming through the tower of a big TV antenna.
I spoke too soon - there are other people here! I passed a sign saying 'exercise area' (zone ushtarake), and I can hear some overly-enthusiastic people playing paintball. It's a great place for it, with all the old bunkers and other fortifications.
Now I'm going to relax, enjoy the sun and scenery, and write some postcards.
