Triskele Symbol or Triskelion. I think its more popularly know as the Triple Spiral.
This is a trilateral symbol consisting of three interlocked spirals. This is known to be one the oldest Irish Celtic symbols. It was discovered on the Newgrange kerbstones.
Newgrange is a prehistoric monument in County Meath, Ireland. It is a grand passage tomb built during the Neolithic period around 3200 BC. Thus makes it older than both Stonehenge and the Egyptian pyramids.
Triskeles feature prominently in ancient and modern Celtic art. The three spirals symbolise the trinity. Whether its the realms of material existence, earth, water and sky. Or spiritual, physical and celestial.
If you read more on the Triskele you find many more interpretations.
