This cache will take you to one of the three Fortress Observation Posts (FOPs) that are placed in the Port Elizabeth area. These FOPs were built in 1940 at the beginning of the Second World War.
At the time of the construction of the buildings they were covered with the typical Eastern Cape coastal bush. As a result, it was decided to incorporate into the designs of the more prominent structures a curvy, free-form profile of parapets, angle buttresses and 'fins' to break up the square, box-like shape of these buildings when seen from the sea against the background of the bush. This curvy profile extended to the flat roofs, projecting floor slabs and even the concrete paths leading to the FOPs, so that the view of these structures from the air would be similarly disguised. In addition, the parapets around the flat roofs of the FOPs were loopholed for close defence by small arms.
Fortunately for Port Elizabeth, these defences were not put to the test as, apart from a couple of incidents during the Second World War, when it was found necessary to put a round from one of the guns across the bows of a suspicious ship, and the usual practice sessions, the battery did not fire a shot. However, the deterrent effect of the presence of the artillery defences should not be underestimated.
The FOP at Skoenmakerskop is more vulnerable to vandals and 'graffiti artists', but does not appear to be under threat from development at present.
At the FOP, beware of Trevor and Anne! (Trevor and Anne referred to graffiti - that has now changed, and the theme is now "Live life while you can" - still a bit scarey!) Also, please ensure that the cache container is properly sealed - and hidden out of sight.
