The HER says
“A large barrow at Ludworth Intakes was destroyed by ‘treasure- hunters’ when it became known it was to be excavated. According to information volunteered, ashes, bones, etc. were found and also a cinerary urn which was broken and its contents lost. The barrow was alleged to have been divided into three paralled circles one within the other, the centre one containing the urn. ”
Its not destroyed, just mangled like a lot of barrows about these parts.
