Newgrange c. 3200 B.C.

Older than the Pyramids of Giza, Stonehenge, and Newgrange was constructed in the heart of Ireland in County Meath (meaning 'Middle' and once the fifth province) over 5,000 years ago during the Neolithic period. The meaning behind the triskelion concentric spirals and other artworks carved into the stones are lost to time although there are numerous theories. The people who built Newgrange pre-date the Celts, although the art and works they left behind may have influenced the much later Celtic culture and artefacts. The cruciform chambers inside were also decorated and held the remains of ancient people. There is also an alignment with the sunrise during the Winter Solstice every December 21.
