Although the dragon has been used in Wales for many years, it wasn't until the 20th century that it became an official symbol.

In 1901 the dragon became the official symbol of Wales, and in Caernarfon in 1911, at the investiture of Edward, Prince of Wales, the flag appeared in its current form, helping its rise to prominence.

In 1959, after successful lobbying by the Gorsedd of Bards and others, Queen Elizabeth II made the red dragon on a green and white background the official flag for Wales.

It was announced that the flag to be flown on government buildings would consist only of the red dragon on a green and white flag, rather than the 1953 badge, which was still in occasional use.

The 1959 design can today be seen right across Wales, and is a symbol of pride in history and heritage for Welsh people across the world.
