The Boyne Valley is home to Ireland's most sacred ancient monuments. The valley surrounding the Boyne River is easily one of the most history-laden pieces of land on an island replete with historic sites. Dating back as far as the 35th century BC (before the pyramids were countenanced) are the myriad of mounds and monuments of Brú na Boinne (Palace of the Boyne), including the extraordinary passage tomb at Newgrange which is lit up with perfect precision by the rising sun on the Winter Solstice.

Patrick lit the first Easter fire in Ireland. He was immediately summoned to the King (on the nearby Hill of Tara), Laoire (Leary) who, while never converting himself to the new religion of Christianity, allowed St. Patrick to set forth on ministry around his pagan land.

James decamped to Ireland; William followed. On 1 July 1690, the two faced each other across the River Boyne . Twelve hours and some 1,500 deaths later, James retreated, never to return to Ireland or England again.
