St David's Flags

The flag of Saint David (Welsh: Baner Dewi Sant) is normally a yellow cross on a black field, although it has also appeared as a black cross on a yellow field, or with an engrailed cross. It has been used as a flag representing Wales (as an alternative to the Red Dragon flag), in the same sense that the crosses of Saint George, Saint Andrew, Saint Patrick and Saint Piran are used to represent England, Scotland, Ireland and Cornwall (of which they are, respectively, patron saints).
