Newgrange tomb is what is called a passage tomb, which means that it contains a narrow passage made of stone and earth and containing several burial locations. Beyond simply being a passage tomb, it is a site of historical importance.
It is a spiritual and ceremonial representation of the people who lived in Ireland over 5,000 years ago when it was constructed! Newgrange was carefully constructed, showing evidence of a society that understood concepts of construction and that was well-organized.
It is a kidney-shaped mound and has an inner passage that is 19 meters long. It covers over an acre of land. In the passage is a cross-shaped chamber with a corbelled roof. It also has 97 curbstones decorated with art. It has been called a World Heritage Site by UNESCO.
Newgrange is one of several similar constructions that are built along the River Boyne. Together these structures are known as Brú na Bóinne. Knowthl is the largest of the mounds, but there are about 35 other smaller mounds.
