The Giants Causeway tartan was inspired by the Causeway area. The Giants Causeway is a World Heritage Site situated near the famous village of Bushmills, Northern Ireland, and attracts around 750 000 visitors annually. It is formed of basalt columns created by molten lava crystallizing as it came into contact with the sea. The colours in the tartan represent the colours of the surrounding area: shades of grey for the basalt columns, sea blue for the Atlantic, white for the surf and green for the hinterlands.
