I do always like a challenging question!
Well we all know that the Guernsey Flag is a mix of
the Cross of St George and the Cross of William the Conqueror - Duke of Normandy.
But last week a gentleman who was a keen history buff
said he had never seen Williams cross before, stopping to think about it neither had I.
Later in town I bumped into the Head of Museums here, and so I asked him.
Turns out in 1066 William persuaded Pope Alexander 2 to send him a papal banner,
to show him backing of Williams invasion plans.
As you can see it is definitely the gold cross from the center of our flag.
It also features a fair few time in the Bayeux Tapestry, though you do seem to have to know what you are looking for, its not obvious.
So we now know, and I bet you anything I am never asked that question again!!!!!
