Saint Patrick on the Hill of Slane
Long established tradition tells that St. Patrick lit the Easter Fire on this Hill of Slane in 433. In doing so, he unwittingly disobeyed King Laoghaire at nearby Tara.
The inevitable confrontation had a happy outcome: Laoghaire's druid, Erk, became a Christian (later, first Bishop of Slane) and the King was pacified.
The Easter Fire is still lighted, each year, on the Hill of Slane.
