The Celtic spiral at Newgrange, County Meath, is one of the most famous examples of ancient Irish art. Built around 3200 BCE by the banks of the River Boyne, Newgrange passage tomb is older than Stonehenge and the Egyptian pyramids. The spiral decorative rock art and is thought to represent both artistic and spiritual significance to the earliest settlers in Ireland.

The spirals are carved onto the entrance stone at the passage tomb entrance and include both single and triple spiral designs. The triple spiral, or "triskele," has become an iconic symbol often associated with Celtic art, though its origins here predate the Celts. Archaeologists believe the spirals could symbolize the cycles of life, death, and rebirth or the natural movement of the sun and moon. This aligns with Newgrange’s alignment to the winter solstice, when sunlight illuminates the tomb's inner chamber, suggesting a connection between the spirals and the cyclical nature of time or the journey of the soul.

Today, these spirals remain powerful symbols of Irish heritage and spirituality, embodying the mystery and artistry of Neolithic people.
