Site near Tara, seat of Irish kings, approved for demolition

On June 14, 2007, construction resumed on a four-lane highway near the Hill of Tara in central Ireland. Traditionally the seat of the high kings of Ireland, the landscape is littered with burial mounds, rock art, earthen enclosures, and stone monuments. Tara, which has been described as Ireland's equivalent of Stonehenge, was named one of the 100 most endangered sites by the World Monuments Fund this year.

The Irish government met resistance when it announced plans for a 60 km road running straight through the Gabhra Valley between Tara and the nearby Hill of Skreen. Archaeologists and historians claimed that the entire valley, not just the hill, contains historical monuments and artifacts and should therefore be protected.

In its defense, the National Roads Association (NRA) argued that a new road was necessary because the existing N3 highway is deteriorating, thereby making travel dangerous and inefficient for drivers between Dublin and Navan. A deal was signed with Eurolink, an independent contractor, and construction began in Spring 2006.

The M3 proposal was heavily criticized, especially after the recent discovery of Lismullin, a ceremonial enclosure located on the edge of the valley, just 2 km (1.24 mi) away from Tara. It is thought to be from the Early Iron Age, which would make it at least 2,000 years old. The site consists of an outer enclosure 80 m in diameter and an inner enclosure 16 m in diameter. Both are bounded by two rings of stakeholes, suggesting that they were initially made from timber. It has been argued that the presence of a ritual site in the Gabhra Valley confirms earlier claims that Tara is a complex of historical monuments, and not only an isolated hill.
