Although found mostly in Western Europe, a ''Passage Tomb'' was an early (possibly Neolithic, 12,000 BC) form of burial location, which involved the placement of The Dead into underground caverns, which had hand-hewn corridors, leading to a surface entrance. The entrances to Passage Tombs would feature various stone monoliths, often arrange in patterns meant to invoke protection from The Gods against Tomb Violators. In Irish Mythology, Passage Tombs were seen as being access points used by the mythical and elusive Tuath De Dannan, to traverse between ''this World'' and ''the Next''. This may have been the ultimate goal of the true meaning of The Passage Tombs. Souls could ''come and go'' thru The Tombs, and these locations were seen as being sacred and off limits to all save Shamans and Kings.
