This is probably the biggest gun emplacement currently open to the public, and is in fact part of a series of emplacements along the headland, most of which can be visited. Visiting hours can be a little erratic, as the site is run by a dedicated team of volunteers, so it is best to check online for the opening hours. This impressive bunker was the Command Post (Leitstand) for the naval coastal artillery. The bunker included a range-finder and two periscopes to determine the distance and speed of sea targets. Amongst the memorabilia on show at the site are weaponry, uniforms, communications and cutlery. There are also articles about those in residence at the bunker and many items that depict the relationship the German soldiers had with the island.
