According to my trusty old The Oxford Dictionary of English Place-Names by Eilert Ekwall ( 1960) the Houghton in then Huntingdonshire is a Hōh-tūn, ‘tūn on a spur of hill’. So I’m guessing that’s how that “beacon on a hill that still overlooks the whole region” came into it.
Not, alas hearg-tūn which would mean ‘tūn associated with a Heathen shrine’ but hey you can’t have everything...
I wonder. Do we know if any security measures are being taken? The archaeologists may know some special reason why nothing like the Staffordshire Hoard is likely, in this instance, but nighthawkers and treasure hunters might not know or believe it. Hate to think they could come in to work one morning to find some ruddy great hole(s) dug, destroying valuable information.
