5,000-year-old building gets new anti-slip decking
The Knowth Megalithic Passage Tomb in Europe is older than the Eygptian pyramids. The Megalithic sites of the Boyne valley which include Knowth, Newgrange and Dowth were designated a world heritage site by UNESCO in 1993. Artifacts including pottery and flint discovered in the surrounding area of the Great Mound of Knowth date back beyond 4,000 B.C. Visitors can enter the tomb through several of the great tunnels that stretch in excess of 34 meters each.
