## Route description

Leave Dublin on the N3 to the Hill of Tara, where the High Kings of Ireland were crowned. Little stands above ground, but the earthworks and the view over the plains of Meath explain its importance.

Continue to Trim, where the largest Anglo-Norman castle in Ireland stands beside the river Boyne. Follow the river downstream on the N51 through Navan to Slane; climb the Hill of Slane, where St Patrick is said to have lit his Easter fire.

Newgrange and Knowth are visited only on guided tours from the Brú na Bóinne visitor centre, reached by shuttle bus. Arrive early in summer as tours sell out; the tombs are older than Stonehenge and the pyramids of Giza.

Drogheda has a medieval gate and a church with the relics of St Oliver Plunkett; the site of the Battle of the Boyne is at Oldbridge, just west of town. End at Monasterboice, where Muiredach’s High Cross stands among the graves beside a round tower.
