C. Rock carving exemplifying common abstract swirls and symbols
Step-by-step explanation:
Newgrange is a circular building of 85 meters in diameter and 13.5 meters in height. The building is over 5,000 years old, and was built during the Neolithic period, around 3,200 BC.
Newgrange is older than the Egyptian pyramids, which were built around 2,700 BC.
Newgrange was built to serve as a religious temple for the farming community that inhabited the rich Boyne Valley land where the temple is located.
Newgrange appears to have been used primarily as a tomb. Cremated human remains were found from five individuals. However, today, many scholars agree that Newgrange was not only a tomb, but was also used for religious ceremonies and rituals.
The grassy mound that covers the tomb is surrounded by 97 stones and geometric shapes such as spirals and triangles are drawn on them.
