It’s in a very dramatic setting, right up on a little headland, sticking out between two wide sandy beaches popular with surfers. It’s next to a massive concrete structure which was probably some kind of war emplacement. As well as a central passage it’s got five chambers; they’re a bit difficult to ‘read’ as the monument is in some state of disrepair, but it’s well worth going to see it for it’s gorgeous seaside location alone.
