Newgrange in modern Ireland

To me the most wonderful examples of Irish art are the passage tombs of Newgrange and Knowth. Built over 5,000 years ago, they are museums of neolithic art work and engineering. The people who began these projects were so committed that they were prepared to give their lives to the building of these monuments that they would never see completed. What was their function and why were they abandoned so soon after their completion?
 We know that they were used to house the cremated remains of the dead but we do not know how many or few were interred. What we do know is that about one hundred years later Newgrange had lost all its visual impact and was only seen as a grassy hill on the landscape. It lay in that state until 1699 when by chance a local farmer sent his workmen to the mound to collect stone to build a road. By sheer chance as the men began to dig they came upon the highly decorated entrance stone. Had they started from any other point they probably would have destroyed the mound before they would have realised what they had come upon. The result was that the road material had to be taken from somewhere else and that Newgrange was saved. Or was it? Because it was now open for all to enter its sacredness was compromised. Animals sheltered inside the tomb and some of the cremated remains were lost. Eighteenth century graffiti artists engraved their names and date on the precious stonework and these are still visible today. Newgrange remained in that state until Michael J O'Kelly, an archaeologist from Cork gave thirteen summers to excavating part of the mound. His work resulted in stabilising the passage and chamber and opening up the roof box to allow the rays of the sunrise during the winter solstice to penetrate the mound. But a decision had to be made to redesign the front of the mound to allow access by steps so as not to damage the entrance stone. Some people disagree with that decision but if this had not been done it would now be closed to the public.
Knowth has an even more interesting history. The Celts dug trenches behind its kerbstones, damaged them and shortened the passages, the Christians dug tunnels (souterrains) to hide from the Vikings, and the Normans built forts on top of it. It too became a grassy hill on the landscape until Professor George Eogan began its excavation about 50 years ago. What is there today is a fully excavated and reconstructed passage tomb secured for the future with the use of modern materials and supports.
Have we compromised these sacred sites? Do the benefits of having them preserved for our future children outweigh the intervention? I believe so.
Today people are arguing that the proposed Slane bypass could threaten the status of Brú na Bóinne as a Unesco world heritage site. The road will be 3.5km away from Newgrange and I fail to see how this could impact on the mound or its sister tombs. The proposed bridge will only be a dot on the landscape in front of Knowth. When these tombs were first build the areas around them were covered in dense forests. Surely a few well places trees could block out a view of a modern bridge. On the other hand one of the most exciting images is the view of Newgrange from the road as you drive towards the heritage centre. I would quite like to be able to see Knowth from a bridge in the distance.
But the most serious side of all of this is the human cost. "There are 22 white crosses set on the wall on the Mill Hill which represent the number of people killed on the roads in Slane over the last 40 years. The last fatality was in 2001 when a two-year-old child was killed. A truck crushed him to death when it mounted his mother’s car while she was stopped at traffic lights on the Mill Hill.
