Union Jack Flag - Official Flag of the United Kingdom #1611989 (License: Personal Use)

The Union Jack features a composite design of three heraldic crosses: the red cross of St George (England), the white saltire of St Andrew (Scotland), and the red saltire of St Patrick (Ireland). Its proportions are 1:2, and it is used officially on government buildings, naval vessels, and during national events. Though Wales is not represented separately, its inclusion is acknowledged through historical union.
