Y Ddraig Goch, or the Red Dragon, is a symbol of Wales and features prominently on the national flag. The dragon is believed to represent strength and power, and its origins can be traced back to ancient mythology and folklore. The image of the red dragon is linked to the legend of Merlin, who foretold a battle between a red dragon and a white dragon, symbolizing the struggle between the Welsh and the Saxons. Today, Y Ddraig Goch is a proud emblem of Welsh identity and heritage.
