Fact Ten: The Largest Ancient Stone Monument In Britain?
However surprising and unlikely it may seem, the evidence is that Garn Goch is, indeed, the largest ancient stone monument in Britain.
Largest: bigger in area than any other ancient stone monument in Britain. Not the most important or complex, but largest, yes.
Ancient: technically, prehistoric (before the age of writing and recorded history).
Stone: made with stone and rocks, not earth and soil.
a) a statue, building, or other structure erected to commemorate a notable person or event;
b) a statue or other structure placed over a grave in memory of the dead;
c) a building, structure, or site that is of historical importance or interest.
So, an Iron Age fort? Not ancient (they had writing in the Iron Age), nor a monument.
What about, say, Hadrian's Wall? Originally an earthworks not made of stone, not ancient, not a monument.
Stonehenge? Ancient, yes. Stone, yes. Monument, yes. Larger in area than Garn Goch? No.
