Mace Head On the headland of Mace the lookout post no.46 is situated at the road end to Crosspatrick at Halfmaceon. During the second world war coast watcher reports the activities around that area. The logbooks from this lookout post are open today for public at the Irish Defence Forces website militaryarchives.ie. At the historic photo the telephone wire mast is cognizable which connected the lookout posts during the ww2. In fact of the telephone connections the Defence Forces was able to create a motion profile of marina and airspace activities. At this light projection geometric pattern was selected to sense the perception of the geometric building structure.
