Brú na Bóinne - Archaeological Ensemble of the Bend of the Boyne
The three main prehistoric sites of the Brú na 
Bóinne Complex, Newgrange, Knowth and Dowth, are situated on the north 
bank of the River Boyne 50 km north of Dublin. This is Europe's largest 
and most important concentration of prehistoric megalithic art. The 
monuments there had social, economic, religious and funerary functions.
