And while we're at it, let's remember that the battle was fought not at Hastings but seven miles NW, at Senlac, near what is now Battle.
But since it would be daft, and anachronistic, to call it the Battle of Battle, Hastings it is.
I am reminded of the number of rivers called Avon, which means river (British/Welsh avon/afon). I have this mental image of a Saxon asking a passing Briton what a river is called, and the grumpy Brit thinking he's being asked what the actual physical feature is. "Daft foreign bugger," he says to himself, "can't he see it's a river?" "Avon," he yells, and so it is named.
But I digress. The Tapestry is well worth a journey to see. Vaut le voyage.
