The mound’s main construction is late Neolithic, not medieval
Claim about Merlin’s Mound (Marlborough Mound) · Stance: supporting
Modern coring and radiocarbon dating indicate that the main body of the mound was built in the later 3rd millennium cal BC. Earlier interpretations as a purely Norman castle motte are therefore incomplete; the castle phase represents later reuse of a much older monument.
