Hook Head The post was situated close to the Hook Head lighthouse. Today only the shapes of the concrete fundament remain to the lookout post no.16. Close to the post a huge Eire sign was also written in the ground white colored stones. The Eire signs supported the allied aeronautic in navigation during the second world war. It has the appearance that all remains of the post are cleared. That gave the inspiration to project a keep clear zone on the concrete fundament. The statement also leans against that idea that it may never again be necessary to watch for war activities on that shore.
