There's a rough video here which shows the Toothill Long Barrow in Halliwell, Bolton. There's no doubt about its authenticity but it is suppressed, for various reasons. It's 80m. long, 25m. wide and a little over six high. It's part of an ancient farmed landscape and is unknown.

Comments welcome - there is a What 3 Words link in the description.

"Suppressed for various reasons"??

Is this the barrow David Aspinall talked about 10-15 years ago? I keep meaning to dig that out.
Only 10 mins from my house so I'd love any more details etc. My email is in my profile if you want to share stuff more privately!

Thanks to everyone that watched this video. I expected fifty views. hoped for a hundred and got about eighty, so far.

I've found that it is fairly common for bank barrows to be aligned north-south and that there is a pair of parallel bank barrows in Germany.

My next YT vid will probably be a throwaway action comedy called Searching For A Megalinch where I travel to Edinburgh to find one of Thom's Megalithic Inches in the basement of the National Scottish Museum.
