The ancient burial chamber at Newgrange is attacked by vandals who leave a Campaign for Nuclear Disarmament symbol behind.
Newgrange in County Meath is famous for its dramatic lighting spectacle at sunrise on the Winter Solstice, when the sun shines directly into the chamber.
Newgrange is one of Ireland's most important monuments. It's been there for five thousand years. It's older even that the great Egyptian pyramids.
While nothing dramatic normally happens at summer solstice, on the morning of the 20 June 1987 staff found that that lock on the gate to the main burial chamber had been tampered with. Vandals also took some quartz stones from a pit on the site and placed them at the entrance to the chamber. The stones were arranged in the shape of the CND (Campaign for Nuclear Disarmament) symbol. There were also some stones removed from the main wall.
Claire Tuffy, supervisor at the monument, spoke to RTÉ News about the security at Newgrange.
There is nothing to prevent people vandalising any public building except their sense of responsibility to the fact that this is probably one of our most ancient and most sacred of places.
With up to a hundred thousand visitors to the site each year, Claire Tuffy says that this is the first time there has been such an incident which she puts down to the respect shown to the site by the public.
