I think you'll find that the Cornish border hasn't moved for hundreds of years.
The salient? of the English incursion was a gift to someone or other up in the Bridgerule area.
My mate - since had a stroke and lost of much his historical information coz he was a whizz at all this - would have told me the facts.
The area used to be in Cornwall until the 12th? century as the border followed the River Tamar, but now England comes in across it.
Residents have been asked on many occasions if they'd like to be part of Cornwall, but they have consistently voted No.
Virginstow and St Giles have nothing to do with that as they are south of the incursion.
I fancy a ride this week. Mercian this time instead of Moulton, and I'll do both those parish churches.
One of my "tasks" a few years back, was to ride over all the bridges over the River Tamar.
Twenty-three in all, and done them.
Maybe I might do them all again!
If you go north from Whitstone to Red Post, you cross into England and back into Cornwall, but historically, you would still be in Cornwall ........ but history is a long time ago.
