If you take a map of mainland Great Britain, cut it out neatly, and balance it on a pin, the point that makes it perfectly level is near Haltwhistle in Northumberland. Yes, a town famous for having a wall—Hadrian’s—and a name that sounds like you’re coughing.
This is the centroid, the actual geometric center. It’s technically correct, which is the worst kind of correct. But nobody throws a parade for a spot in a sheep field.
