The Union Jack features overlaid crosses of St George (England), St Andrew (Scotland), and St Patrick (Ireland) on a blue field with red and white accents.

Flag fun fact: The Union Jack's design combines three national crosses, with St Andrew's cross placed diagonally behind St George's cross to create the distinctive interlocking pattern.
