I have actually wondered this since I was in high school. You see, the British flag is composed of three “crosses”: the cross of St. George (red “+” on a white field, representing England), the cross of St. Andrew (white “X” on a blue field, representing Scotland) and the cross of St. Patrick (red “X” on a white field, representing Ireland, or Northern Ireland now). (Here they are all together.)
My question just involves the cross of St. Patrick. Why is shown off-center like that? Look at the flag again more carefully, and you will see what I mean. I vaguely recall hearing somewhere this is so no cross will take prominence over the others. But what does that mean? Why would putting it off-center prevent this. And why is the cross of St. Patrick the only cross that they do this with ?
