What is a passage tomb?
There are many examples of different types of megalithic monuments from the Neolithic period. Chamber tombs are one type of Neolithic structure, and passage tombs are a sub-category of chamber tombs.
A chamber tomb simply means that the megaliths were arranged to form a chamber within. Dolmens are one example of a chamber tomb (see image below).
A chamber tomb is considered a passage tomb when the structure is more developed. Passage tombs, also often called passage graves, often resemble a hill or mound when viewed from a distance. Sometimes the only means of telling the difference between a hill and a passage tomb is by the entryway outlined in stone (as you will see below).
